A new way to enhance the porosity and Y-faujasite percentage of in situ crystallized FCC catalyst

Methane decomposition catalysts for COx-free hydrogen production

“…There are reports on supported systems with active metal components such as Ni (Matsukata et al 1996, Li et al 1997, Zhang and Amiridis 1998, Aiello et al 2000, Choudhary and Goodman 2000, Ermakova et al 2000, Choudhary et al 2001a,b, Otsuka et al 2001, Ermakova and Ermakov 2002, Inaba et al 2002, Piao et al 2002, Takenaka et al 2002, Otsuka et al 2003, Takenaka et al 2003a,b, Fukada et al 2004, Reshetenko et al 2004b, Zavarukhin and Kuvshinov 2004 (Li et al 1997, Ogihara et al 2006, Chai et al 2007, Ichi-oka et al 2007, Odier et al 2007), Ir (Ogihara et al 2006, Ichi-oka et al 2007, Odier et al 2007), Pt (Ashcroft et al 1991, Odier et al 2007), Ag (Chai et al 2007) and Os (Ichi-oka et al 2007). Since then, the process has been studied extensively, especially at lower temperatures in the presence of catalysts.…”

Sulfonic acid catalyst based on silica foam supported copolymer for hydrolysis of cellulose

“…For example, the silica surface was post-grafted with organosilanes [7][8][9]. Tetraalkoxysilanes ((RO) 4 Si) and trialkoxyorganosilanes ((RO) 3 SiR) were co-condensed to prepare periodic mesoporous organosilicas (PMOs) with bridging organic groups in the framework [10][11]. In both cases, the organic groups were further functionalized with sulfonic acid.…”

“…Among them, zeolites have attracted a lot of attention, but the narrow pore size has been considered as an important drawback [3][4]. To host bulky molecules, great efforts have been made to design large pore sizes aiming to expand the applications.…”

2D Semiconductor Bi2WO6 Nanosheets as the Pt Carriers for Ethylene Glycol Oxidation Reaction with Photoelectric Interaction

“…[16][17][18][19] Bismuth tungstate (Bi 2 WO 6 ), with a unique layered structure has received great interest for its promising chemical and physical properties. [20][21][22] In addition, with a narrow bandgap of 2.74 eV, [16] Bi 2 WO 6 leads to its inherent visible-light absorption capability, which benefits for the visible photocatalytic degradation of organic pollutants and water splitting. [23][24][25][26][27][28] However, as all the aforementioned applications of Bi 2 WO 6 focus on the photocatalytic reactivity, it is desirable to further extend the application of Bi 2 WO 6 .…”
