The migration behavior of electron and hole pairs determines both photoluminescence and photocatalytic activity, which are two distinct properties of semiconductor materials. The photoluminescence and photocatalytic activity of semiconductor materials also exhibit strong method-dependent behavior under the influence of synthesis methods. In this review, the synthesis methods of MMoO, MWO and MMoO/MWO (M = Mg, Ca, Sr and Ba) heterojunction composites and their photoluminescence and photocatalytic activities are reviewed for the first time. The effects of different M ions on the photoluminescence and photocatalytic activity of MMoO/MWO heterojunction composites are also reviewed. There is also a discussion about the intrinsic correlation mechanism between photoluminescence and photocatalytic activity. Different M ions result in different coordination environments in MMoO/MWO heterojunction composites, which leads to different photoluminescence and photocatalytic mechanisms of different MMoO/MWO heterojunction composites. This review provides theoretical reference and technical guidance for future research on MMoOMWO heterojunction composites.

This study investigates the synthesis, characterization, and functional properties of well-aligned zinc oxide (ZnO) nanowires (NWs) obtained by a two-step hydrothermal method. ZnO NWs were grown on silicon substrates precoated with a ZnO seed layer. The growth process was conducted at 90 °C for different durations (2, 3, and 4 h) to examine the time-dependent evolution of the nanowire properties.

Photocatalytic conversion has emerged as a promising strategy for harnessing renewable solar energy in the valorization of plastic waste. However, research on the photocatalytic transformation of plastics into valuable nitrogen-containing chemicals remains limited. In this study, we present a visible-light-driven pathway for the conversion of polylactic acid (PLA) into alanine under mild conditions.

Severe photogenerated charge carrier recombination involved in photocatalytic CO reduction leads to low photocatalytic efficiency. Here we demonstrate that a chiral hierarchical structure could facilitate charge separation in BiOBr, thus suppressing charge recombination and enhancing photocatalytic performance. Chiral helical flower-like BiOBr nanospheres were prepared a D/L-sorbitol-assisted hydrothermal process, exhibiting a 1.

This research successfully synthesized semiconductive magnesioferrite (MgFeO) nanomaterials using a green chemistry method that utilizes the natural extract of Moringa olefeira serving as both a reducing and oxidizing agent. The optical characteristics and crystalline structure of the MgFeO nanomaterials were analysed using photoluminescence, diffuse reflectance spectroscopy, and X-ray diffraction. Additionally, Fourier transform infrared spectroscopy provided valuable insights into the chemical bonding and composition.
