Summary: Reducing CO2 to hydrocarbon fuels through solar irradiation is a promising approach for mitigating CO2 emissions and resource depletion. However, the catalytic performance is hindered by severe charge recombination and high energy barrier. In this study, a 2D/2D Bi2MoO6/BiOI composite was fabricated to enhance CO2 photoreduction efficiency. The composite showed efficient charge transfer, strong redox capability, and effective charge separation. The intermediates of CO2 photoreduction were identified, and the rate-determining step for CH4 and CO production was determined to be CO2 hydrogenation. Introduction of Bi2MoO6 decreased the energy barrier for CO2 photoreduction on BiOI. The study highlights the synergistic effect of the S-scheme heterojunction and van der Waals heterojunction in the 2D/2D composite.

Summary: A quadratically nonlinear photodetector (QNPD) composed of a van der Waals (vdW) stacked GaSe/InSe heterostructure is reported in this study. The QNPD exhibits unique electronic and optical attributes and extends the photodetection wavelength range from 900 to 1750 nm due to the extra second-harmonic generation (SHG) process in GaSe/InSe. It is highly sensitive to the variation of optical intensity and can be used as an autocorrelator for measuring ultrafast pulse widths and an optoelectronic mixer for signal processing.

Summary: We report an oxygen vacancy (V-o)-rich metallic MoO2-x nano-sea-urchin with partially occupied band, which exhibits super CO2 photoreduction performance under UV, visible and NIR light. The V-o-rich MoO2-x nano-sea-urchin shows significantly higher CH4 evolution rate compared to the V-o-poor MoO2-x, and can even reduce CO2 directly from the air. Experimental and theoretical results suggest that the oxygen vacancy in MoO2-x facilitates CO2 adsorption/activation and subsequent protonation of *CO towards the formation of CH4 due to the formation of a highly stable Mo-C-O-Mo intermediate.

Summary: This study investigates the influence of vacancy engineering on intrinsic CO2 photoreduction with low photon energy directly from air. The authors designed a metallic photocatalyst, V-S-AgInS2 nanocrystals, which exhibited superior atmospheric CO2 reduction performance under near-infrared light. The presence of sulfur vacancies and metallic characteristics in the nanocrystals resulted in extended spectrum absorption and efficient charge carrier separation. The experimental and theoretical results showed that charge delocalization around the vacancy-induced dual sites promoted CO production while inhibiting the formation of CHO intermediates. Consequently, the metallic VS-AgInS2 nanocrystals achieved nearly 100% selective CO production under NIR irradiation.
