The structural properties of these catalysts were characterized by means of XRD,XPS,TPR and SEM,and the photocatalytic activity was evaluated with the degradation reaction of acetic acid and photocatalytic reduction of carbon dioxide as probes.

• 利用XRD；XPS；TPR等手段对不同样品进行了表征；以乙酸水溶液的光催化氧化降解及二氧化碳光催化还原为反应探针；对3种催化剂光催化活性进行了评价.
