methanotrophic Hpr confirmed a key role of the enzyme in utilization of C1-compounds via the serine cycle. The enzyme from Ms. trichosporium OB3b realizing the serine cycle as a sole assimilation pathway had much higher special activity and affinity in comparison to Hpr from Mm. alcaliphilum 20Z and Mc. capsulatus Bath assimilating carbon predominantly via the ribulose monophosphate (RuMP) cycle. The hpr gene

The C3selectivity of carbon‐supported Au nanoparticles for glycerol electro‐oxidation was significantly enhanced by the interaction of Au with electro‐deposited Cu species. Notably, the C3selectivity of supported Au nanoparticles doubled after 90 min of Cu electro‐deposition at +0.015 V. This result was obtained if glycerol electro‐oxidation was performed at +0.1 V for 2 h. The most selective catalysts

durability of the catalyst. The fuelcell using the PdZn/TiO2−x NS catalyst showed a high power density of 855 mW cm−2, which exceeds that of the PdZn supportedcarbon catalyst. Also, the proposed catalyst showed excellent stability over more than 100 h in proton-exchange membrane fuelcell (PEMFC) performance. Thus, the proposed TiO2−x NSs will be an alternative to a carbonsupport in future PEMFC technology
探索简单灵活的方法合成具有高催化活性的氧还原反应(ORR)催化剂,对于燃料电池的大规模应用具有重要意义。在这里,我们通过涉及低温退火的浸渍工艺大规模生产的简单策略,在 TiO 2- x NS 载体催化剂上开发了金属间化合物 PdZn 。这种通过简单一步制备的电催化剂在室温下在酸性和碱性溶液中均表现出更好的 ORR 活性,具有更高的电化学活性表面积 (ECSA)。在 80°C 下重复方波电位循环测试超过 10000 次循环证实了催化剂的耐久性。使用 PdZn/TiO 2- x的燃料电池NS 催化剂显示出 855 mW cm -2的高功率密度,超过了 PdZn 负载的碳催化剂。此外,所提出的催化剂在质子交换膜燃料电池(PEMFC)性能中表现出超过100小时的出色稳定性。因此,所提出的 TiO 2- x NS 将成为未来 PEMFC 技术中碳载体的替代品。此外,与 PdZn/C 相比,PdZn/TiO
