The regulatory effect of Al atomic-scale doping in NiAlO for COS removal

Tuning product selectivity ofCO2hydrogenation byOHgroups on Pt/γ‐AlOOHand Pt/γ‐Al2O3catalysts

“…Thus, Pt nanoparticle could bond to O in Sites B and C of supports, without interaction to OH of supports, on 2Pt/AOH and 2Pt/AOH200. This agrees well with DFT calculation results (Figure2E) and literature which showed that (Site B)-Al-(Site C) bridge sites on γ-AlOOH are preferred for metal nanoparticle nucleation and growth 21,22. At (Site B)-Al-(Site C) bridge sites, Pt nanoparticle bonds to coordinated saturated O in Site B and coordinated unsaturated O in Site C to form Pt-support interface (Figure2E).…”

Preparation of a NiAl‐Oxide@Polypyrrole Composite for High‐Performance Supercapacitors

“…The disappearance of the NiAl‐LDH reflections was attributed to the removal of interlayer CO 3 2− anions, dehydration and dehydroxylation of the host layers from the NiAl‐LDH. No Al‐based phases were detected due to the homogeneous dispersion of Al species in the NiO lattices . As for the NiAlO@PPy, the main peaks were similar to those of the NiAlO, while a broad reflection was assigned to the pure PPy.…”

“…The NiAl‐LDH indicated the characteristic features of the layered double hydroxide structure with (003), (006), (009), (110), and (113) crystal planes, where no other crystalline phases were detected and the interlayer space ( d 003 =0.778 nm) was described to be a typical CO 3 2− ‐pillared layered double hydroxide . After the calcination at 450 °C, the NiAl‐LDH crystalline phase was gradually transformed into NiAl bimetallic oxide, and the NiAlO showed the characteristic reflections of the NiO phase correspond to (111), (200), (220) and (311) crystal planes, as reported in the literature . The disappearance of the NiAl‐LDH reflections was attributed to the removal of interlayer CO 3 2− anions, dehydration and dehydroxylation of the host layers from the NiAl‐LDH.…”

Removal of ethyl mercaptan from gas streams using chromium modified hexaniobate nanotubes

“…27 The peak located at ∼380 °C belongs to medium strength alkali sites, which are related to the chemical bonds between metal niobium and oxygen. 28 After chromium loading and calcination, the peak intensity corresponding to weak alkali decreases, indicating that the hydroxyl groups on the surface of nanotubes are gradually consumed with the increase of chromium loading. In addition, a new CO 2 desorption peak appeared at ∼550 °C, which belongs to strong alkali sites.…”
