摘要: 本文设计采用盐酸处理石墨相氮化碳(g-C3N4)，获得质子化石墨相氮化碳，并用光沉积的方法在石墨g-C3N4上负载Ni(OH)2，合成了Ni(OH)2/g-C3N4复合结构。通过XRD，TEM，XPS，UV-Vis等表征手段和光催化产氢测试，研究酸化处理程度对g-C3N4结构、形貌以及对复合催化剂光催化活性的影响。质子化后复合结构的光催化产氢效率达到1256.5 umol∙g−1∙h−1，相比于未曾质子化的复合催化剂性能提升了接近5倍。
Abstract: In this paper, the graphite phase carbon nitride (g-C3N4) was treated with hydrochloric acid to obtain protonated g-C3N4, and Ni(OH)2 was loaded on the g-C3N4 by photodeposition. The effects of acidification on the structure and morphology of g-C3N4 were studied by XRD, TEM, XPS and UV-Vis. The photocatalytic activity of Ni(OH)2/g-C3N4 composites has reached 1256.5 umol∙g−1∙h−1 after protonation, which was nearly five times higher than that of the composite catalyst without protonation.
