摘      要：Photochemical catalytic processes can reduce the activation energy so that reactions can occur under milder ***,it is still unknown whether photochemical effects are present in photothermal catalysis over conventional transition metal ***,the representative photothermal CO_(2)hydrogenation catalyst,Ni@p-SiO_(2),is employed as a model system to quantitatively probe the contribution of photochemical *** a series of catalytic and photophysical characterizations,it is found that negligible photochemical effect in the ultraviolet-visible region can be observed for the traditional Ni-based *** results of photo-electrochemistry(PEC)test further confirm that no apparent photochemical effect is present for the Ni@p-SiO_(2)catalyst in the aqueous-phase *** has been further evidenced that the photochemical contributions can be significantly amplified by introducing plasmonic metals,such as Au,into the *** work provides a guideline for the design and construction of efficient synergetic photothermal-photochemical catalytic systems.
