In 2018, the two-dimensional (2D) PdSeO monolayer was predicted to be a highly promising photocatalyst for direct overall water splitting in the light of density functional theory (DFT) computations. Herein, we present the first report on the synthesis of 2D PdSeO nanosheets by using the quaternary ammonium intercalation-assisted electrochemical exfoliation method. The resulting atomically thin PdSeO nanosheets possess a moderate band gap with suitable band edge alignments for water splitting, and display excellent activity and stability in photocatalytic H evolution.
2018年，根据密度泛函理论（DFT）计算预测，二维（2D）PdSeO单层是一种极具前景的用于直接全解水的光催化剂。在此，我们首次报道了采用季铵插层辅助电化学剥离法合成二维PdSeO纳米片。所得的原子级薄的PdSeO纳米片具有适中的带隙和适合水分解的能带边缘排列，并在光催化析氢中表现出优异的活性和稳定性。
