摘　　要：Photothermal CO_(2) hydrogenation is a promising route to produce methanol as a sustainable liquid solar fuel.However,most existing catalysts require a combination of solar irradiation and additional heat input to achieve a satisfactory reaction rate.For the few that can be driven solely by light,their reaction rates are one order of magnitude lower.We develop a photothermal catalyst with multilevel interfaces that achieves improvedmethanol production from photothermal CO_(2) hydrogenation without external heat.The catalyst features a layered structure comprising Cu/ZnO/Al_(2)O_(3)(CZA)covered by oxidized carbon black(oCB),where the oCB/CZA interface promotes efficient heat generation and transfer,and the Cu/oxide interface contributes to high catalytic activity.Under a mild pressure of 8 bar,our oCB/CZA catalyst shows a methanol selectivity of 64.7%with a superior production rate of 4.91 mmol-geza-1-h-1,at least one order of magnitude higher than other photothermal catalysts solely driven by light.This work demonstrates a photothermal catalyst design strategy for liquid solar fuel production.
