| 1 | 磷化镍助催化剂修饰石墨相氮化碳促进光催化重整杨树叶制氢性能显示文摘以双氰胺(C_(2)H_(4)N_(4))为原料,采用直接热聚合法制备石墨相氮化碳(g-C_(3)N_(4));以六水合氯化镍(NiCl_(2)·6H_(2)O)和赤磷(P4)为原料,采用简易的水热法将磷化镍(Ni_(2)P)助催化剂负载到二维g-C_(3)N_(4)表面.通过X-射线衍射(XRD)、红外(IR)、透射电子显微镜(TEM)、扫描透射电子显微镜(STEM)、N_(2)吸/脱附、固体紫外漫反射(UV-Vis DRS)、荧光(PL)等,表征所合成催化剂的化学结构、微观形貌及光电性质;以原生生物质杨树叶为牺牲剂,在碱性条件下(3 M NaOH)研究催化剂的光催化重整制氢性能.结果表明:单一的g-C_(3)N_(4)材料无法实现光催化重整制氢,而少量的Ni_(2)P助催化剂负载后可以实现光催化重整制氢;当Ni_(2)P助催化剂负载量为4%(质量分数),杨树叶质量浓度为0.2 g/L时,催化剂展现出最佳的光催化重整制氢活性,平均产氢速率可达3.38μmol/(g·h). | 洪远志 张雪 时君友 李翔宇 | 2021 | 北华大学学报(自然科学版)2021，22，4： | 0 |

| 3 | Surface plasmon resonance metal-coupled biomass carbon modified TiO_(2) nanorods for photoelectrochemical water splitting显示文摘Exploring efficient and stable photoanode materials is a necessary link to realize the practical application of solar-driven photoelectrochemical(PEC)water splitting.Hence,we prepared rutile TiO_(2) nanorods,with a width of 50 nm,which was growth in situ on carbon cloth(TiO_(2)@CC)by hydrothermal reaction.And then,Ag nanoparticles(NPs)and biomass N,S-C NPs were chosen for the additional modification of the fabricated TiO_(2) nanorods to produce broccoli-like Ag-N,S-C/TiO_(2)@CC nanocomposites.According to the result of ultraviolet-visible diffuse reflectance spectroscopy(UV-vis)and PEC water splitting performance tests,Ag-N,S-C/TiO_(2)@CC broadens the absorption region of TiO_(2)@CC from the ultraviolet region to the visible regio n.Under AM 1.5 G solar light irradiation,the photocurrent density of Ag-N,S-C/TiO_(2)@CC is 89.8μA·cm^(-2),which is 11.8 times higher than TiO_(2)@CC.Under visible light irradiation,the photocurrent density of Ag-N,S-C/TiO_(2)@CC reaches to 12.6μA·cm^(-2),which is 21.0 times higher than TiO_(2)@CC.Moreover,Ag-N,S-C/TiO_(2)@CC shows a photocurrent responses in full pH range.It can be found that Ag NPs and N,S-C NPs play key roles in broaden the absorption range of TiO_(2) nanorods to the visible light region and,promote the occurrence of PEC water oxidation reaction due to the surface plasmon resonance effect of Ag NPs and the synergistic effect of N,S-C NPs.The mechanism demonstrated that Ag-N,S-C/TiO_(2)@CC can separate the photogenerated electron-hole pairs effectively and transfer the photogenerated electrons to the photocathode(Pt plate)in time.This research provides a new strategy for exploration surface plasma metal coupled biomass carbon materials in the field of PEC water splitting. | Yingzhen Zhang Yonggang Lei Tianxue Zhu Zengxing Li Shen Xu Jianying Huang Xiao Li Weilong Cai Yuekun Lai Xiaojun Bao | 2022 | Chinese Journal of Chemical Engineering2022，35，1： | 0 |
