Foam nickel yes A sort of high Porous of Material , usually used as The fuel cell , Water and electricity untie and chemical synthesis wait application middle catalytic Material of base material . Foam nickel of high surface area and open structure make That become support catalytic Material and Promote Efficient reaction dynamics of ideal platform . However , Foam nickel of Porosity yes Influence That Catalytic activity of The key factor . therefore , improve Foam nickel of Porosity for improve That catalytic Applicability able crucial .
improve Foam nickel Porosity of main method one yes optimization Foam manufacture Craftsmanship . Foam nickel usually pass electricity deposition arrive Conductive base material superior , Then Remove base material by form porous structure afterlife Produce . pass carefulness control deposition parameter , For example Current density , electrolyte Element and deposition time , Can custom made Foam nickel of pores structure , by optimization That Porosity , by adapt specific of catalytic application . For example , Increase deposition time Can produce Even thick and More interconnection of hole , this Can improve Catalytic activity site of Can and sex and exist porous structure middle supply better of mass transfer .
for promote Foam nickel Porosity , so absolute Can pass implement fine Chemical etching Craftsmanship Come have Selectivity land Cull That surface oxide and he Impurities , and then Construct out more open and structure clear pores network . Tarsus according to Will meeting omnipresent . use high temperature annealing technology not only were able strengthen Foam nickel overall structure stability and Mechanical behavior , besides return able pass Promote grain hyperplasia and pores refine process , indirect accomplish Porosity Increase .
pass exist Foam nickel surface introduce nanometer structure Material like Metal nanometer particles or Metal oxide , besides use carbon coating or carbon support wait Strategy , Goals of method , Can Significantly promote That Porosity and Catalytic activity , and then Enhance catalytic performance .
pass fine Adjustment manufacture process , implement later Add Engineering skills technique as well as implement surface modified Strategy , Goals of method , Can personalise custom made Foam nickel Porosity , by adapt different catalytic application need , need of thing , thereby Significantly promote That Catalytic activity . this one field constantly explore and innovation , constantly of Improve , Will prompt Foam nickel as Efficient and Quite a few use catalytic Material matrix , Feel Comfortable . for promote Can continued energy and Chemical process develop play Key role , operate must cautious .
