Ag-modified α-Fe2O3 spherical particles interspersed on hierarchical flower-like NiAl-LDH microspheres with Z-scheme for significantly enhanced CO2 photoreduction into CO

3D porous flower-like CoAl2O4 to boost the photocatalytic CO2 reduction reaction

“…The full survey XPS spectrum (Fig. 5a) shows the Co, Al, C and O elements, 40 which is consistent with the EDS results. The high-resolution Co 2p XPS spectrum (Fig.…”

Efficient photocatalytic NO oxidation over novel NiAl layered double hydroxide/Bi4Ti3O12 Z-scheme heterojunctions with boosted charge separation and O2 activation

“…35-0795). 30 For pure NiAl-LDH, four distinct diffraction peaks can be observed at 11.70°, 23.60°, 35.17°, and 39.80°, which correspond to (003), (006), (012), and (015) crystal planes of NiAl-LDH (JCPDS 15-0087), 31 respectively. The typical diffraction peaks of Bi 4 Ti 3 O 12 and NiAl-LDH were observed in the prepared NiAl-LDH/Bi 4 Ti 3 O 12 heterojunction, with no other impurity peaks detected.…”

Multiflower-like ReS2/NiAl-LDH Heterojunction for Visible-Light-Driven Photocatalytic CO2 Reduction

“…In contrast, pure ReS 2 exhibited nearly the same branches of adsorption−desorption isotherms with no significant hysteresis loop, which indicated its low porosity. 36 The Brunauer− Emmett−Teller (BET) surface areas, average pore diameters, and total pore volumes are presented in Table S1 (Supporting Information). Obviously, 2-ReS 2 /NiAl-LDH possessed the highest BET surface area of 59.67 m 2 /g and the largest pore volume of 0.42 cm 3 /g, showing that the close combination of NiAl-LDH and ReS 2 has led to an increasing surface area, which would be attributed to more active sites for subsequent photocatalytic reduction reactions.…”
