“…As a part of photoelectrochemical system for the utilizing of solar energy, the performance of photoanode is reliant on light absorption, charge carriers separation and electrolyte/product diffusion . To this end, attempts such as doping or morphology controlling, adding co‐catalysts, designing composite materials have been made, and optimized photoactivity are therefore achieved. While the modification of photoactive materials themselves may not be the only means for optimization of the light utilization efficiency, an alternative way is employing a substrate which can enhance the light utilization of loaded photoactive materials .…”

Optimized Overall Photoactivity of WO₃: Utilization of Incidence Dependence from Photonic Crystal Substrate

In this work, conductive PC-FTO (photonic crystal fluorine doped tin oxide) films are fabricated on commercial FTO substrate. The PC-FTO films serve as two roles: supplying large nan-structural loading sites available for the embedded photoactive materials, and also manipulating the incident light to improve the performance of embedded photoactive materials under specific incidence range. Through facile solvothermal approach, WO 3 platelets are synthesized directly inside the skeleton of PC-FTO to form WO 3 @PC-FTO photoanode which shows more efficiency utilization of light at certain incidence. These homogeneous coating of WO 3 platelets in PC-FTO film allows the study of photonic crystal impact on the photoactivity as a function of incidence.

Towards Solar Methanol: Past, Present, and Future

This work aims to provide an overview of producing value‐added products affordably and sustainably from greenhouse gases (GHGs). Methanol (MeOH) is one such product, and is one of the most widely used chemicals, employed as a feedstock for ≈30% of industrial chemicals. The starting materials are analogous to those feeding natural processes: water, CO 2 , and light. Innovative technologies from this effort have global significance, as they allow GHG recycling, while providing society with a renewable carbon feedstock. Light, in the form of solar energy, assists the production process in some capacity. Various solar strategies of continually increasing technology readiness levels are compared to the commercial MeOH process, which uses a syngas feed derived from natural gas. These strategies include several key technologies, including solar‐thermochemical, photochemical, and photovoltaic–electrochemical. Other solar‐assisted technologies that are not yet commercial‐ready are also discussed. The commercial‐ready technologies are compared using a technoeconomic analysis, and the scalability of solar reactors is also discussed in the context of light‐incorporating catalyst architectures and designs. Finally, how MeOH compares against other prospective products is briefly discussed, as well as the viability of the most promising solar MeOH strategy in an international context.
