2023年4月1日 · In this study, novel hollow highly dispersed Pt/Copper modified-MnO 2 catalysts were fabricated. Cu 2+ was stabilized into the δ-MnO 2 cladding substituting original K +, which produced lattice defects and enhance the content of adsorbed oxygen.

2023年12月14日 · PTOCBAR MNO refers to the text message phishing scam involving supposed unauthorized BDO account payments to a merchant named “PTOCBAR”. MNO likely stands for “mobile network operator”, referring to the mobile provider enabling the scam texts.

2021年10月9日 · Determination of structure and properties suggested that Pt facilitated the formation of more oxygen vacancies/Mn 3+ and surface adsorbed oxygen weakened the bonds of surface lattice oxygen, while Mo stabilized surface lattice oxygen and increased acid sites, especially Brønsted acid sites.

2023年1月4日 · This work demonstrates a more effective Pt-dispersed MnO 2 catalyst than Pt-embedded MnO 2 catalyst for HCHO oxidation, providing universally important guidance for metal–support interaction and interface regulation for oxidation reactions.

2021年10月8日 · Determination of structure and properties suggested that Pt facilitated the formation of more oxygen vacancies/Mn 3+ and surface adsorbed oxygen weakened the bonds of surface lattice oxygen, while Mo stabilized surface lattice oxygen and increased acid sites, especially Brønsted acid sites.

In this study, we discovered that the low-temperature CO oxidation activity over Pt/MnO x catalyst could be enhanced by a novel β-MnO 2 support material. Nearly complete CO conversion was obtained over the Pt/MnO x catalyst below 100 °C under our catalysis conditions.

2021年10月19日 · Determination of structure and properties suggested that Pt facilitated the formation of more oxygen vacancies/Mn 3+ and surface adsorbed oxygen weakened the bonds of surface lattice oxygen, while Mo stabilized surface lattice oxygen and increased acid sites, especially Brønsted acid sites.

2019年2月5日 · Results show that MnO 2 can act as a favorable support and promoter for Pt electrocatalyst and the catalytic properties of Pt are closely related to the morphologies of MnO 2. Among the three MnO 2 nanocrystals, Pt/MnO 2 - R with MnO 2 nanorods as the promoter shows the highest catalytic properties of Pt.

2024年12月1日 · Pt/MnO-NiO is a promising DBFC cathode electrocatalyst, with n of 4 for ORR. Integrating transition metal oxides with precious metals is a strategic approach to designing cost-effective electrocatalysts with enhanced stability.
