摘要: Inherently cationic poly(3-acrylamidoproply)trimethylammonium chloride) (p(APTMACl)) as hydrogel and cryogel nonporous superporous structures to use template for cobalt Nickel metal nanoparticle preparation then H2 production from NaBH4 hydrolysis. Use of p(APTMACl) hydrogels in generation reactions hydrolysis is an advantage due their inherently nature no requirement any modification/quaternization steps load salts situ preparation. However, it very well known that the loading processes are slow. Therefore, super-porous cryogels prepared offered great advantages terms swelling, absorption preparation, higher catalytic activity NaBH4. The composites provide 32, 3600, 1.5, 5.5 3.5 fold faster swelling degree, time, capacity, time rate, respectively than composites. In addition, p(APTMACl)-Co shown have highly useful characteristics reaction NaBH4, innate magnetic character, which allows control by externally applied field, reusability, with almost 80% at end 5th use.
