Thermodynamic analyses and experimental demonstrations were performed to investigate whether cation-exchange reactions (CERs) with metal chloride gases are a feasible technique for forming heterostructures of group-III sesquioxides. The thermodynamic revealed the possibility formation aluminum oxide (Al2O3) layers on gallium (Ga2O3) or indium (In2O3) substrates via CERs gases, as well Ga2O3 In2...

CO2 electrochemical reduction reaction (CO2RR) to formate is a hopeful pathway for reducing and producing high-value chemicals, which needs highly selective catalysts with ultra-broad potential windows meet the industrial demands. Herein, nanorod-like bimetallic In2O3/Bi2O3 were successfully synthesized by pyrolysis of InBi-MOF precursors. The abundant oxygen vacancies generated from lattice mi...

Catalysts for CO2-to-methanol are typically evaluated in a single-pass regime using pure CO2streams. In practical process however, CO shall be present as feed impurity or recycled byproduct. Herein, the sensitivity to was on In2O3 catalysts bulk, supported, metal-promoted forms, cycle experiments with variable CO2 and contents at H2/(CO + CO2) = 4. The methanol productivity decreased (?20-?40 %...

Abstract Indium-based catalysts exhibit excellent performance for CO2 hydrogenation to methanol, yet their nature and chemical evolution under reaction conditions are still elusive, thus hindering an understanding of mechanism. In this work, near ambient-pressure X-ray photoelectron spectroscopy (NAP-XPS) is employed investigate the properties catalytic role indium/copper model conditions. We f...

Semiconductor materials are the basis of electronic devices employed in communication and media industry. In present work, we report synthesis characterization mixed metal oxides (MOs) as p,n-junction photocatalysts, demonstrate correlation between preparation technique properties materials. Solid-state UV-visible diffuse reflectance spectroscopy (UV-VIS DRS) allowed for determination light abs...
