Efficient strategies for solar fuel synthesis and Environmental purification as well as low carbon material manufacturing

(可再生能源和环境净化技术以及低炭技术制备功能材料)

My group works on a few forefront research areas including a microwave-intensified low carbon technology for advanced materials synthesis, H2 fuel production from water and CO2 conversion by solar energy, CH4 conversion and water treatment. This lecture will introduce our recent progress in three key themes.

1) 微波增强的低炭技术制备功能材料: Developing energy efficient, reproducible and high throughput synthetic approaches to functional materials manufacturing has gained increasing attention. Herein crystalline nanostructured metal and metal oxide have been engineered by a novel microwave intensified fluidic system. Microwave irradiation was found to direct the self-assembly of produced hematite subunits via selective heating and polarization of nanoparticles. In parallel, the novel technology could manufacture Au nanoparticles with mean particle of ~4 nm x ~8 nm after 90 second microwave irradiation (Referred to our papers, Green Chemistry, 2016,18 (10), 3057-3065; ACS Sustainable Chemistry & Engineering, 2016, 4 (12), 6435-6442)

2) 太阳能转化为化学能: Solar energy has the potential to meet the increasing global energy demands. Therefore solar energy conversion and storage, via water splitting and CO2 conversion has been attracting substantial interest over the last ten years. The current very moderate efficiency in the photochemical processes is contributed to both fast charge recombination and large bandgap of inorganic semiconductors (Referred to our paper, Chemical Society Reviews, 2017 DOI: 10.1039/c6cs00306k and Chemical Reviews, 2018, 118 (10), pp 5201–5241 and Materials Today, 2018)

Stimulated by our recent research outcomes on the charge dynamics in inorganic semiconductor photocatalysts, we developed novel material strategies for solar driven fuel synthesis by polymer photocatalysts. One is to mitigate the charge recombination by improving the degree of polymerization of a polymer e.g. C3N4. With respect to it, one successful example of pure water splitting in a suspensions solution under visible light has been demonstrated for the first time. The other strategy is to narrow the bandgap of carbon nitrides by bandgap engineering. The material prepared via an oxygen rich organic precursor has a dark color, resulting into an efficient H2 production from water by UV and visible, even IR light with a quantum yield (QY) of 10% at 420 nm, which is the first example of a polymer photocatalyst working in such long wavelength for H2 fuel production. (Referred to our papers, J. Am. Chem. Soc., 2008, 130(42) 13885-13891. J. Am. Chem. Soc., 2014, 136, 12568-12571. Angewandte Chemie International Edition, 2014, 53, 9240-9245. Energy Environ Sci, 2017, DOI: 10.1039/C7EE01109A, J. Am. Chem. Soc. 2017, 139 (14), 5216–5224. Angewandte Chemie International Edition, 2017, 10.1002/anie.201703372, Energy Environ Sci, 2018, 10.1039/C7EE02981K)

3) 光催化污水处理技术: To develop an efficient photocatalyst for catalytic environmental purification, still remains a big challenge, involving Material Science, Chemistry, Engineering and Physics. In particular there is not a cost effective way to deal with large volume of water contaminated by small amount of organic substance or large amount of contaminated water in suburban region (e.g. oil spill in Mexico Gulf and in China Bohai Sea). Inorganic photocatalysis using solar energy to mineralize organic contaminants in principal is the best solution to these issues and works in a cost effective way. The mechanism of the chemical process will be addressed in the talk and structured/junction materials development will be presented, resulting into nearly double activity of the benchmark photocatalyst P25. Furthermore, a facile method to synthesize these active photocatalysts will be discussed.
