Fabrication of Pd/γ-Al2O3 catalysts for hydrogenation of 2-ethyl-9,10-anthraquinone assisted by plant-mediated strategy

Bio-inspired synthesis of metal nanomaterials and applications

“…318 The maximum H 2 O 2 yield of 96.4% could be achieved at lower reaction temperature (40 1C) than those in the literature. Recently, green and reusable Pd/g-Al 2 O 3 catalysts for 2-ethyl-9,10-anthraquinone hydrogenation were fabricated by the AR method with C. Platycladi extract as both a reductive and a protective agent.…”

Fabrication of supported Pd–Ir/Al2O3 bimetallic catalysts for 2‐ethylanthraquinone hydrogenation

“…In the hydrogenation of eAQ, it has been reported that a decrease in Pd particle size can lead to enhanced yields of H 2 O 2 . 37,38 Moreover, enhancing the adsorption of the C5O moiety at the expense of C5C adsorption can be expected to inhibit the over-hydrogenation of eAQH 2 . Therefore, the synergistic inter-metallic interactions in Pd-based bimetallic catalysts, especially Pd-Ir bimetallic catalysts, offer the promise of simultaneously increasing both H 2 O 2 yields and selectivity.…”

Synthesis of hydrogen peroxide over Pd/SiO2/COR monolith catalysts by anthraquinone method

“…Today, more than 99% of hydrogen peroxide is commercially manufactured by the anthraquinone method, including the 2-ethyl-9,10-anthraquinone (eAQ) hydrogenation process and the autoxidation process of 2-ethyl-9,10-anthrahydroquinone (eAQH 2 , one of products of eAQ hydrogenation process), while the catalytic hydrogenation of eAQ process is the key step [3][4][5][6][7][8]. As the target product of hydrogenation of eAQ process, eAQH 2 is formed in the quinone-hydroquinone stage but undergoes further hydrogenation reaction.…”
