Design composite oxide supported Pt catalyst for catalytic wet air oxidation of ammonia with a high concentration in chloride system

Selective Hydrogenation of Phenolic Compounds to Cyclohexanols over Nanosheet Ni@Al2O3 Catalysts

“…All catalysts’ N 2 adsorption and desorption curves are similar and belong to type IV of the IUPA classification. At a relative pressure of between 0.5 and 1.0 ( P / P 0 ), the N 2 adsorption–desorption isotherm of catalysts calcined at 400–600 °C displayed a hysteresis phenomenon with an H2-type hysteresis loop . The 20%Ni@Al 2 O 3 -800 catalyst with a H3-type hysteresis loop appeared at a relative pressure of about 0.4–1.0 ( P / P 0 ).…”

“…At a relative pressure of between 0.5 and 1.0 (P/P 0 ), the N 2 adsorption−desorption isotherm of catalysts calcined at 400−600 °C displayed a hysteresis phenomenon with an H2-type hysteresis loop. 43 The 20%Ni@Al 2 O 3 -800 catalyst with a H3-type hysteresis loop appeared at a relative pressure of about 0.4−1.0 (P/P 0 ). The hysteresis loop of the 20%Ni@Al 2 O 3 -700 catalyst is in the transition stage between the two.…”
