摘要

通式为 (A1)4(A2)2C4M10O30 的 K6M10.8O30（M = Ta、Nb）在四方钨青铜结构中具有部分填充的 C 位点，在负载适当的共催化剂后，在紫外线照射下具有光催化裂化水的活性。在 248 纳米波长下，优化的 NiO（0.2 wt%）负载 K6Ta10.8O30 在水分离方面的表观量子产率为 13%。

Photocatalytic water splitting over K6M10.8O30 (M = Ta, Nb) with a partially filled tetragonal tungsten bronze structure

K6M10.8O30 (M = Ta, Nb) with partially filled C sites in a tetragonal tungsten bronze structure represented as the general formula (A1)4(A2)2C4M10O30 shows photocatalytic activity for water splitting under UV light irradiation upon loading with suitable cocatalysts. An apparent quantum yield of the optimized NiO(0.2 wt%)-loaded K6Ta10.8O30 for water splitting is 13% at 248 nm.
