Water and graphene generate electricity to successfully light up LED bulbs

Do you believe that when graphene is combined with water, or will open a new energy revolution?

Recently, Professor Qu Liangti from Beijing Institute of Technology, Dongxu Optoelectronics Co., Ltd. and his team successfully lit the LED bulbs with electricity generated by water and graphene. Let us once again praise the science.

Energy conversion efficiency up to 62% Graphene + Water = New Energy Revolution

On February 17th, the international authoritative academic journal Nature reported the recent graphene research results of the team of Professor Qu Liang, entitled “Energy from Water and Graphene”.

"Nature" magazine published the results of graphene research by Professor Qu Liangti

In addition, the research results are also published in the recent issue of Energy and Environmental Science.

According to the article, Professor Qu Liangti from Beijing Institute of Technology and his team developed a three-dimensional structure made of graphene oxide, which has a large enough pore to allow water molecules to pass freely. When water flows from the top of the material to the bottom, the water molecules will react with the oxygen-containing groups in the graphene oxide to separate and form hydrogen ions; the remaining oxygen groups are non-uniformly distributed in the material. This will generate enough ions to generate Electrical energy.

According to estimates, the conversion efficiency of this energy conversion method is as high as 62%. Based on this technology, Professor Qu Liangxu designed and manufactured a humidity sensor that uses the humidity change of the human body as a power source to detect the human respiratory characteristics under different motion conditions, and realizes self-powered instant human health monitoring for the first time.

At the same time, based on the above findings, it can also be converted into a directly usable electric energy by capturing the chemical potential energy contained in the humidity diffusion process in the air, which opens up a brand new potential energy source and has considerable prospects in the field of new energy.

The scientific community generally believes that with the gradual reduction of fossil fuel reserves and increasing environmental pollution, new environmentally friendly energy conversion technologies have shown great potential in the development of new generation energy generation systems.

It is understood that Professor Qu Liangti is a Distinguished Professor of the Ministry of Education and a recipient of the National Outstanding Youth Fund. He is mainly engaged in the research of nano-nano materials with carbon-carbon conjugated structures, involving carbon nanotubes, graphene, conductive polymers, etc. Controllable preparation, functional modification and its application research. He presided over the National Natural Science Foundation's Outstanding Youth Fund, the Surface Project, and the National Major Basic Research and Development (973) Program.

Up to now, Professor Qu Liang has published more than 130 papers in international important journals such as Science, Angew. Chem. Int. Ed., Adv. Mater., J. Am. Chem. Soc., Nano Lett. More than 3000 times. Among them, the research results of "carbon nanotube array bionic gecko feet" published in Science opened a new chapter in the field of nano-bionics.

For the partners, we are strong and strong, and jointly promote the application of graphene industrialization.

While working on cutting-edge scientific research, Professor Qu Liangti actively cooperates with enterprises to promote the application of graphene industrialization. According to the data, its R&D team teamed up with the leading graphene company Dongxu Optoelectronics in 2014 to create the “Dongxu Photographene Technology Research Institute”. In March 2015, the two parties also jointly established the first domestic technology research and development, project incubation and industrial operation platform for graphene new materials - Beijing Xu Carbon New Materials Technology Co., Ltd. (referred to as: Xu Carbon New Materials), indicating that The graphene industrialization application project entered the final sprint.

Wang Zhonghui, head of Dongxu Optoelectronics Investment, said that he is very optimistic about the future application prospects of Professor Qu Liangti, a major technological breakthrough in energy conversion. He said that the joint venture company Xuan Carbon New Materials is also paying close attention to the research and application of graphene in energy conversion and storage. For example, lithium battery anode research project is a study of energy storage.

It is reported that the three invention patents of the North Polytechnic Technology Co., Ltd. shares in the Asahi Carbon New Material Joint Venture Company are controlled assembly preparation techniques of graphene materials of different dimensions, and can prepare systemic synthesis of three-dimensional graphene functional membranes from one-dimensional graphene fibers to substrates. The method has laid a high technical starting point at the beginning of the project company startup.

"At present, the research and development of some graphene projects of the joint venture company has entered the pilot stage." Dongxu Optoelectronics Dong Ge Gong said that Dongxu photoelectric graphene application currently has three directions: 1. Transparent conductive film; 2. Heat-dissipating film; , lithium battery anode material. Up to now, the lithium battery anode material is the most promising to make a breakthrough. If it is fast, it will see a performance contribution this year.

Dongxu Optoelectronics Co., Ltd. is the largest high-tech enterprise integrating LCD glass substrate equipment manufacturing, technology research and development and product production and sales. Its industrialization application around new graphene materials has been explored and laid out very early. In December last year, it participated in the establishment of the “Beijing-Tianjin-Hebei Graphene Industry Development Alliance” as a leading company in the domestic graphene industry investment layout.

In addition, Dongxu Optoelectronics also established Beijing Dongxu Huaqing Investment Co., Ltd. in April last year with China's graphene industry technology innovation strategic alliance to strengthen the development of information exchange, resource integration, strategic planning, marketing and other fields. Cooperation to create a professional graphene investment and financing platform.

At the end of October last year, the “Dongxu Optoelectronics” Cup 2015 China International Graphene Innovation and Entrepreneurship Competition was held in Qingdao. The graphene discoverer and the 2010 Nobel Prize in Physics, Professor Andre Geim, attended and accompanied Wang Zhonghui. In-depth exchanges and discussions on the future prospects of graphene research and development cooperation.
