|To mimic the natural plant synthesizing energy from H2O and CO2 using solar energy, lots of research efforts have been conducted to realize efficient artificial photosynthesis to solve the energy crisis using biology photochemistry and/or inorganic photoelectrochemistry. In this presentation, I would like to walk the audience through a thorough review of history in this research area covering some of the most important revolutionary discoveries and research milestones in both of the aforementioned directions. After this, I would like to focus on the development of artificial photosynthesis using inorganic semiconductor photoelectrochemistry with recent breakthroughs. In UCSD, PI's (Prof.Deli Wang) group is focused on using nanoscale materials for this application. Advantages of using regular array of nanoscale devices comparing to traditional planar device include larger surface area, better light utilization, more efficient charge carrier transportation and collection, smaller amount of materials needed and more. I will share some of my recent work in terms of nanomaterial synthesis and characterization, and most importantly their applications to photoelectrochemical cell, which is actually the first step in photosynthesis.|
