非贵金属磷化钼催化甲醛制氢

Non-precious metal molybdenum phosphide catalyzed hydrogen production from formaldehyde

通过简单的固相磷化法合成了非贵金属MoP催化剂。通过XRD、SEM、EDX和BET对催化剂进行了表征。结果发现:惰性气氛下,MoP催化剂对分解甲醛制H2表现出优异的性能,60 min反应连续放氢,放氢量达到1150 mL,制氢活性优于贵金属。这一结果为寻找廉价的分解甲醛制氢催化剂开辟了新思路。

The non-noble metal MoP catalyst was synthesized by a simple solid-phase phosphating method.The catalyst was characterized by XRD,SEM,EDX and BET.The results showed that the MoP catalyst showed excellent performance for the decomposition of formaldehyde to H2under an inert atmosphere.The hydrogen released continuously for 60 min, and the amount of hydrogen production reached 1 150 mL.The hydrogen production activity was better than that of precious metals.This provides a new idea for finding an inexpensive catalyst for decomposing formaldehyde to H2.
