Polyoxometalate-Intercalated Tremella-Like CoNi-LDH Nanocomposites for Electrocatalytic Nitrite–Ammonia Conversion

“…55 It can be observed that the typical peaks of P 8 W 48 can be clearly found in the spectra of P 8 W 48 /CoNi-LDH, and the tungsten−oxygen vibration peaks are slightly shifted (the peaks at 1055 cm −1 for W�O t , 930 cm −1 for W− O b −W, 813 cm −1 for W−O c −W), which should be caused by the formation of hydrogen bonds between the −OH group of CoNi-LDH and the terminal oxygen of inserted P 8 W 48 . 56 In the case of CoNi-LDH, the adsorption bands appearing at 636 57,58 The sharp absorption peak at 1381 cm −1 corresponds to the typical flexural vibration peak of NO 3 − existing between LDH galleries. 59 Compared with that of CoNi-LDH, the NO 3 − absorption peak intensity of P 8 W 48 /CoNi-LDH is significantly weakened, indicating that most of the interlayer NO 3 − has been successfully replaced by P 8 W 48 .…”

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

“…Layered double hydroxides (LDHs), comprising divalent and trivalent metal cations, are a notable class of layered metal hydroxides. Their uniform cation distribution, tunable anionic composition, and favorable visible-light response have garnered considerable attention, demonstrating significant promise in photocatalytic CO 2 reduction. − However, the photocatalytic efficacy of LDHs alone is often hampered by the swift recombination of photoinduced carriers . Therefore, in addition to regulating the morphology of LDHs and employing them as a precursor for calcination or reduction, − combining LDHs with other semiconductor materials to construct heterojunctions has become an efficient strategy to solve the above problem. − Among the wide range of LDH alternatives, NiAl-LDH is distinguished by its flower-like spherical morphology, which not only serves as an excellent structural base for incorporating additional semiconductors but also enhances carrier mobility .…”

Precise Lattice‐Strain Modulation of Hematite Enabled by Gradient Doping of Mn for Enhanced Photoelectrocatalytic Oxidative C─C Bond Scission

“…The lattice strain effect has also been shown to be used to modulate the adsorption/desorption capacity between substrates and catalyst surfaces, which has become a common strategy for improving electrode performance. The activity of CO 2 reduction, OER, and water splitting can be controlled by modulating the stress relaxation properties of the electrode [ 46–51 ] There is limited research on the modulation of lattice strain by doping to improve the performance of photoelectrodes and regulate their reactivity toward organic small molecules (biomass derivatives) in PEC. Quantitative analysis is thus highly necessary to establish the correspondence among lattice strain effect, electronic structure, and substrate adsorption/desorption capacity, providing a thorough conformational elucidation for the efficient PEC oxidative breaking of C─C bond in 1,2‐diols.…”
