Synthesis and evaluation of novel Cu-based adsorbent-containing catalysts for CO<sub>2</sub> hydrogenation to methanol and value-added products
منشور في 2024"…<p dir="ltr">In this work, sequential incipient wetness impregnation method was used to synthesize Cu/Al<sub>2</sub>O<sub>3</sub>, Cu/Na<sub>2</sub>O/Al<sub>2</sub>O<sub>3</sub> and Cu/CaO/Al<sub>2</sub>O<sub>3</sub> catalysts in different compositions for CO<sub>2</sub> conversion to value-added products. Synthesized catalysts were characterized using various analytical techniques and their performances for CO<sub>2</sub> catalytic conversion were tested in a high-pressure packed bed reactor under reaction conditions of P = 60 bars, T = 300 °C, and H<sub>2</sub>/CO<sub>2</sub> = 3. …"

In-situ grown ternary metal hydroxides@3D oriented crumpled V₂C MXene sheets for improved electrocatalytic oxygen evolution reaction
منشور في 2024"…In essence, this study features a facile approach for the confined growth of multi transition metal hydroxides in the presence of morphologically unique 3D crumpled V₂C MXene architectures. Consequently, the increased OER reaction kinetics and improved stability of the synthesized composites are potentially due to synergistic interplay between well dispersed active sites and the conductive substrate.…"
