As a semiconductor, MgWO has a potential in photocatalytic applications; however, it has been overlooked in previous studies; in this study, it has been demonstrated that MgWO exhibits the ability to drive photocatalytic hydrogen evolution. Compared to nanoparticle structures, MgWO nanoplates show an increased photocatalytic ability due to their higher specific surface area. Moreover, the formation mechanism of MgWO nanoplates has been discussed. An oriented attachment and ripening process is proposed for the formation of the MgWO nanoplates. This study demonstrates that MgWO can be considered a valuable photocatalytic material, and future studies should be focused on how to promote its photocatalytic conversion efficiency.
作为一种半导体，MgWO在光催化应用中具有潜力；然而，它在以往的研究中被忽视了；在本研究中，已证明MgWO具有驱动光催化析氢的能力。与纳米颗粒结构相比，MgWO纳米片由于其较高的比表面积而表现出更高的光催化能力。此外，还讨论了MgWO纳米片的形成机制。提出了一种用于MgWO纳米片形成的定向附着和熟化过程。本研究表明MgWO可被视为一种有价值的光催化材料，未来的研究应集中在如何提高其光催化转化效率上。
