“…Meng et al [139] synthesized a novel CuAlO x /CNTs (CNTs = carbon nanotubes) catalyst by facile one-step carbothermal reduction decomposition method for low-temperature NH 3 -SCR. The CuAlO x /CNTs catalyst was found to exhibit higher NO x conversion (>80%) and N 2 selectivity (>90%) than the CuAlO x in the temperature range of 180-300 • C (Figure 26a).…”

The importance of the low-temperature selective catalytic reduction (LT-SCR) of NOx by NH3 is increasing due to the recent severe pollution regulations being imposed around the world. Supported and mixed transition metal oxides have been widely investigated for LT-SCR technology. However, these catalytic materials have some drawbacks, especially in terms of catalyst poisoning by H2O or/and SO2. Hence, the development of catalysts for the LT-SCR process is still under active investigation throughout seeking better performance. Extensive research efforts have been made to develop new advanced materials for this technology. This article critically reviews the recent research progress on supported transition and mixed transition metal oxide catalysts for the LT-SCR reaction. The review covered the description of the influence of operating conditions and promoters on the LT-SCR performance. The reaction mechanism, reaction intermediates, and active sites are also discussed in detail using isotopic labelling and in situ FT-IR studies.

“…Hence, in a reducible gas (H 2 ), the Cu 2+ and Fe 3+ of Fe(NO 3 ) 3 /Cu-MOF could be directly reduced under high-temperature heating to Cu 0 and Fe 0 , respectively. However, in an inert gas (N 2 ), the Fe(NO 3 ) 3 /Cu-MOF underwent pyrolysis carbonization and carbothermal reduction, 40 which reduced Cu 2+ and Fe 3+ to Cu 1+ /Cu 0 and Fe 2+ / 3+ (Fe 3 O 4 ), respectively.

“…The peak at low temperature was attributed to the reduction of the highly dispersed CuO particles with smaller size, while the peak at high temperature was ascribed to the reduction of crystalline CuO with bigger size or strong interaction between CuO and the carrier. 23,41 Therefore, the reduction behaviors of the copper-based catalysts were significantly affected by the interaction of copper species with the carrier and the dispersion of copper species on the surface of the carrier. The dispersion of Cu active sites was further investigated with N 2 O chemisorption.…”

Selectively hydrogenating the carbonyl of furfural and opening of the furan ring is challenging but crucial for efficient conversion of furfural to pentanediols, the valuable chemicals. In this study, CuMgAl catalysts with highly dispersed Cu particles and tunable basic sites were synthesized with layered double hydroxides as precursors for hydrogenation of furfural to furfuryl alcohol (FA) and the subsequent hydrogenolysis of FA to 1,2-pentanediol and 1,5-pentanediol. The presence of varied content of Mg in the catalyst promoted dispersion of copper oxide and exposure of metallic copper species, weakened interaction between copper oxides and the carrier, suppressed sintering of metallic copper species, and increased abundance of the basic sites, promoting the catalytic activity/selectivity/stability. Strong chemical adsorption of the furan ring in FA on basic sites of the catalyst suppressed hydrogenation of the furan ring and facilitated opening of the furan ring in FA, the rate-determining step for formation of the diols.
