Carbon-incorporated mesoporous NiO/TiO (NiO/TiO/C) hybrid shells as low-cost and highly efficient visible light photocatalysts have been developed. The NiO/TiO/C hybrid shells were synthesized by choosing polystyrene nanospheres as templates, followed by TiO and NiO coating, and finally the calcination post-treatment to carbonize PS with the aid of metal oxides. Polystyrene nanospheres serve dual purposes as both a template to ensure the hollow structure and the electrically conductive graphite carbon source. Evaluation of their photocatalytic activity by organic pollutes (rhodamine B, methylene blue, and phenol) degradation and H production under visible light demonstrated the superior photocatalytic performance, thanks to the enhanced visible-light absorption and exciton separation associated with the incorporation of electrically conductive graphite carbon.
碳掺杂介孔 NiO/TiO（NiO/TiO/C）杂化壳作为一种低成本、高效的可见光光催化剂被开发出来。NiO/TiO/C 杂化壳是通过选择聚苯乙烯纳米球作为模板，然后进行 TiO 和 NiO 涂层，最后在金属氧化物的辅助下进行碳化 PS 的煅烧后处理而合成的。聚苯乙烯纳米球有两个作用，既是保证空心结构的模板，也是导电石墨碳源。通过可见光下有机污染物（罗丹明 B、亚甲基蓝和苯酚）降解和 H 2 生成评价其光催化活性，由于导电石墨碳的掺入增强了可见光吸收和激子分离，表现出了优异的光催化性能。
