In this paper,a catalyst of hollow PdCu alloy nanocubes supported on nitrogen-doped graphene support(H-PdCu/ppy-NG)is successfully synthesized using a simple one-pot template-free method.Two other catalyst materials such as solid PdCu alloy particles supported on this same nitrogen-doped graphene support(PdCu/ppy-NG)and hollow PdCu alloy nanocubes supported on the reduced graphene oxide support(H-PdCu/RGO)are also prepared using the similar synthesis conditions for comparison.It is tested that among these three catalyst materials,H-PdCu/ppy-NG gives the highest electrochemical active area and both the most uniformity and dispersibility of H-PdCu particles.Electrochemical tests show that H-PdCu/ppy-NG catalyst can give the best electrocatalytic activity and stability towards the ethanol electrooxidation when compared to other two catalysts.Therefore,H-PdCu/ppy-NG should be a promising catalyst candidate for anodic ethanol oxidation in direct ethanol fuel cells.

牛仔服装洗水是其价值实现的重要工艺过程,传统工艺高消耗与污染的特点使其饱受诟病.臭氧洗水是一种新型的洗水方法,用臭氧代替含氯氧化剂等洗水牛仔服装可以达到省水节能与保护环境的目的.本文研究了臭氧洗水工艺时间对纯棉牛仔与涤棉混纺牛仔服用性能的影响,结果显示两种面料的K/S值在臭氧处理后会因为处理环境中臭氧含量的变化而发生波动,即先增大后减小;处理后,面料的透气率下降,但在前10min时浮色进入到纤维后
