Dinuclear metal synergistic catalysis （DMSC） has been proved powerful in boosting CO2reduction,while this has not been achieved in heterogeneous catalysts with long-range order *** this study,we,by introduction of metal catalytic centers into an indium-based metal-organic framework （MOF）,obtained a series of isostructural In-MOFs,including three MOFs with mononuclear metal catalytic center （M-In）,three MOFs with dinuclear homometallic catalytic centers （MM-In）,and three MOFs with dinuclear heterometallic catalytic centers (MM’-In,M/M’=Co（II）,Ni（II）,Zn（II）).It was found that all these MOFs can serve as catalysts for photochemical CO2reduction to *** with M-In,the catalytic activities of MM-In were obviously enhanced,and that of MM’-In was further significantly *** example,the CO yield of Co Zn-In reaches a record value of 12,700μmol g-1h-1,which is 4.0,8.1,9.4,and 18.6-fold higher than that of Co Co-In,Zn Zn-In,Co-In,and Zn-In,***,the catalytic activities of Co Ni-In and Ni Zn-In also show different fold increase than those of corresponding dinuclear homometallic and mononuclear metallic *** results of control experiments and theoretical calculation reveal that the higher catalytic activities of MM-In over M-In can be ascribed to the DMSC effect,and the higher catalytic activity of MM’-In over MM-In can be ascribed to the strengthened DMSC *** work reveals the relationship between DMSC effect and bimetal centers in CO2reduction,which provides new insights into the DMSC and paves a new way to design highly active catalysts for photochemical CO2reduction.

为促进平面交叉口的行人交通安全,本文基于美国国家电气制造商协会(NEMA)的双环相位标准,将行人专用相位(EPP)、行人同步保护相位(CYPP)以及行人前置相位(LPI)这3种行人保护策略整合到一起,以信号周期和行人-右转车的冲突点数量最小化为目标,构建交叉口信号配时优化模型。在假定交通参与者遵守信号规则的前提下,除LPI策略中远端行人与右转车冲突外,其余冲突点经模型优化后皆可消除,并且机动车的通行效率能够得到维持。该模型属于0-1混合整数线性规划问题(BMILP),可用分支定界法求解。选取南京市两个交叉口进行实例研究。结果表明:在交叉口几何尺寸及交通流量较小时,模型倾向于得到EPP方案,否则倾向于得到CYPP和LPI方案;在进口道设有直右共享车道或右转相位不易满足最大饱和度限制时,模型倾向于得到LPI方案。
