Selective Photocatalytic production of CH4 Using Zn-Based Polyoxometalate as a Nonconventional CO2 Reduction Catalyst.
We report the synthesis of Zn-based polyoxometalate (ZnPOM) and its application in the photocatalytic CO2RR. Unlike conventional Zn-based catalysts that produce CO, ZnPOM can selectively catalyze the production of CH4 in the presence of an Ir-based photosensitizer (TIr3) through the photocatalytic CO2RR.

Modulating Charge Separation Efficiency of Water Oxidation Photoanodes with Polyelectrolyte-Assembled Interfacial Dipole Layers.
In this article, we and co‐workers describe an approach to enhance the charge separation efficiency of water oxidation photoanodes by the interfacial dipole layer created by modifying their surface with polyelectrolyte multilayers assembled via a layer‐by‐layer technique. This approach is effective regardless of the pH and type of photoelectrodes, and potentially provides insights into the design and fabrication of efficient solar‐to‐chemical energy conversion devices.

Modular Layer-by-Layer Assembly of Polyelectrolytes, Nanoparticles, and Molecular Catalysts into Solar-to-Chemical Energy Conversion Devices.
In this article, we and co‐workers suggest the fabrication of solar‐to‐chemical energy conversion devices using a layer‐by‐layer assembly method. Rational and precise assembly of plasmonic and upconversion nanoparticles, polyelectrolytes, and molecular catalysts enables more efficient light‐harvesting, surface passivation, and catalysis, respectively, for solar water oxidation.

Interface Engineering of Hematite with Nacre-Like Catalytic Multilayers for Solar Water Oxidation.
Tailored assembly of polyelectrolytes, graphene oxide nanosheets, and molecular inorganic catalysts into a nacre-like multilayer structure is used to fabricate efficient water oxidation photoanodes. The deposition of nacre-like catalytic multilayers on hematite facilitates both the separation of photogenerated charge carriers and interfacial electrochemical reactions, enabling efficient photoelectrochemical water oxidation under mild conditions.

Fully Solution-Processable Cu2O-BiVO4 Photoelectrochemical Cells for Bias-Free Solar Water Splitting.
We could successfully fabricate an efficient and stable photoelectrochemical (PEC) cell for unassisted solar water splitting without the use of toxic/hazardous chemicals and energetic processes, which have been inevitably employed. A fully solution-processable bias-free PEC cell was readily prepared by using a Cu2O photocathode and a BiVO4 photoanode, which were modified with catalytic multilayers (CMs) for hydrogen and oxygen evolution reactions (HER and OER), respectively, using simple and versatile layer-by-layer (LBL) assembly.
