Mass production of high-quality graphene is the footstone of graphene industry. We focus our efforts on chemical vapor deposition (CVD) growth of graphene films over 12 years, starting from lab-scale samples to pilot-scale products and further to commercial products. Fast progresses are also made on the home-built CVD equipments and production lines for meeting the versatile demands of graphene size, quality and production capacity. Our star products include, A3-size graphene films with a single crystalline domain size of ca. 500 micrometers and a production capacity of 10,000 m2/year, 4-inch single crystal graphene wafers with a capacity of 10,000 wafer/year, 10cm x 30cm superclean graphene films with a capacity of 1000 m2/year. Peeling off CVD graphene from growth metal substrate to target substrate is technically very challenging especially for large size graphene films. We have designed our batch-process systems fitting for different graphene products and also provide customized service for special substrates. A support team with a size of over 70 members has been created in Beijing Graphene Institute (BGI), covering R& D, equipment manufacturing, production line and marketing, targeting to provide the best quality CVD graphene products and production lines to the world.

Photocatalysis has been widely developed and put into practical use in the areas of antifouling and antifogging,research on artificial photosynthesis—the process of extracting hydrogen through photocatalysis—has also been garnering significant attention in recent years as a technology with the potential to contribute to a decarbonized society.
Along with the shift to replace fossil fuels with renewable energies such as hydrogen ,another important measure to achieving a decarbonized society is carbon recycling, effectively using CO2 as a resource. In consideration of that viewpoint, I has proposed the following method: first, extract hydrogen through water electrolysis using the electricity produced from highly efficient solar cells. Next, combine the extracted hydrogen with the CO2 emitted from power plants and factories to produce methanol, which can be used as an energy source.
