Nhanganyaya uye Pretreatment yeNickel Foam

Nickel foamchinhu chakanakisa-inobata ruzha ine yakakwira kunyura coefficient pamhepo huru; kuita kwayo kunobata ruzha pane yakaderera frequencies inogona kuvandudzwa nemagadzirirwo echimiro chinobata ruzha. Nickel foam zvakare imwe yeakanakisa electrode zvinhu zvecadmium-nickel mabhatiri uye hydrogen-nickel mabhatiri. Nickel foam pachayo ine akawanda akanakisa maitiro. Kwete chete kwayo chaiyo giravhiti yakaderera zvakanyanya, asiwo yayo chaiyo nzvimbo idiki kwazvo; huremu hwayo pachayo ndeye-ultra-light, iyo ine huwandu hwakasiyana-siyana hwemashandisirwo eminda uye tarisiro yekushandisa. Usati washandisa, inofanira kunge isati yarapwa. Chete nekutanga kurapa simbi inogona kunyatso vandudza yayo yega simba rekushandisa.

Nickel foam pretreatment: Furo renickel rinochekwa kusvika paukuru hunodiwa hwesample rozoiswa mumushonga we3.0 mol/L HCl kwemaminetsi makumi maviri kubvisa oxide layer pamusoro payo. Zvadaro, thenickel foamyakabviswa, yakashambidzwa kakawanda neanhydrous ethanol uye ultrapure mvura, yakaomeswa zvakasununguka, ndokuzoiswa mu anhydrous ethanol ndokuisa parutivi. Kana iyo electrolyte iine acidic, nickel foam haifanirwe kushandiswa se substrate.
