Sulfur-doped graphitic carbon nitride (S-g-CN) has gained significant attention in recent years. Sulfur-doped graphitic carbon nitride (S-g-CN) is a promising metal-free photocatalyst because of its band orientation, natural abundance and groundwork. Improved photocatalytic activity of S-g-CN material for solar chemical production persists a hot yet challenging problem. Herein, we provide an adaptable method for the synthesis of S-g-CN nanocomposite decorated with the moiety of giant polyoxometalate (S-g-CN/Mo-368) that subsequently showed highly efficient photocatalytic activity. The as-synthesized S-g-CN/Mo-368 as a recyclable artificial photocatalyst revealed excellent activity for solar chemical production, that is nicotinamide adenine dinucleotide (NADH) regeneration under visible light. The immobilized Mo-368 on the S-g-CN surface increased the visible light adsorption capacity of the S-g-CN/Mo-368 photocatalyst. The visible light absorption activity, morphology, element compositions, particle size and zeta potential of S-g-CN powder and S-g-CN/Mo-368 were thoroughly investigated. From the application point of view, S-g-CN/Mo-368 was applied to determine the solar chemical production (i.e. NADH regeneration) under visible light with a higher yield% of about ~ 94.85%.

用于太阳能光下协同再生 NADH 的高效 Sg-CN/Mo-368 催化剂

近年来，硫掺杂石墨氮化碳（Sg-CN）引起了人们的广泛关注。硫掺杂石墨氮化碳 (Sg-CN) 是一种很有前途的无金属光催化剂，因为它具有能带取向、天然丰度和基础。提高用于太阳能化学生产的 Sg-CN 材料的光催化活性仍然是一个热门但具有挑战性的问题。在此，我们提供了一种适应性强的方法，用于合成装饰有巨型多金属氧酸盐 (Sg-CN/Mo-368) 部分的 Sg-CN 纳米复合材料，该复合材料随后显示出高效的光催化活性。合成后的 Sg-CN/Mo-368 作为可回收的人造光催化剂显示出优异的太阳能化学生产活性，即烟酰胺腺嘌呤二核苷酸 (NADH) 在可见光下的再生。在 Sg-CN 表面固定化 Mo-368 提高了 Sg-CN/Mo-368 光催化剂的可见光吸附能力。对Sg-CN粉末和Sg-CN/Mo-368的可见光吸收活性、形貌、元素组成、粒径和zeta电位进行了深入研究。从应用的角度来看，Sg-CN/Mo-368被用于测定可见光下的太阳能化学生产（即NADH再生），产率%较高，约为~94.85%。
