The electrocatalytic conversion of carbon dioxide (CO2) into valuable chemicals presents a promising strategy for closing the carbon cycle. In this study, we synthesized zinc (Zn) catalysts through hydrothermal methods using either polyvinylpyrrolidone (PVP) or cetyltrimethylammonium bromide (CTAB) as stabilizing agents. These catalysts proved highly efficient in converting CO2 into carbon monoxide (CO).

A fabrication technique using Al2O3-passivated local contacts was employed to produce narrow-bandgap CuInSe2 (CISe) photoabsorbers, which are well-suited as bottom cell materials in tandem devices. In this study, for the first time, we attempted to improve the photovoltaic conversion efficiency (PCE) of CISe solar cells by adding a Al2O3 passivation layer.

The present objective of this work is to find photoactive materials capable of facilitating visible light-driven redox reactions between CO2 and H2O. Our research is primarily focused on the incorporation of nitrogen (N) into the crystal lattice of titanium dioxide (TiO2) and its deposition onto Fe-MIL-88B to improve light absorption properties, minimize recombination of photo-generated electron-hole pairs, and increase CO2 adsorption capacity.

In this paper, a multifunctional metamaterial (MM) structure capable of performing as a polarization converter and absorber is proposed. By using DC bias voltage to control the capacitor of the integrated varactor, the near-field coupling in our structure can be manipulated to flexibly switch between polarization conversion (PC) mode and perfect absorption (PA) mode.
