“…These results implied that the high In‐OH signal intensity was probably derived from oxide surfaces other than the framework In. This speculation was further supported by the results of the O1s energy spectrum (Figure 1J), showing that the In‐beta‐TEAOH contained the most non‐lattice oxygen other than water with respect to In‐OH [14] . In contrast to the In3d signal peak in In 2 O 3 @SiO 2 concerning the oxide, the In‐beta‐TEAOH showed a significant high‐energy shift, which corresponded to the blue shift in the UV/Vis spectra of the oxide in mesopores (Figure 1K).…”

The chemically catalyzed production of fructose syrup from high concentrations of glucose is crucial for the food industry and biorefining. In this work, a single crystal catalyst was synthesized via protective desilication of zeolite while incorporating indium. Glucose was isomerized in methanol at concentrations as high as 33 wt.% before being hydrolyzed with water. The final fructose production was 54.9%, with 89.1% selectivity and 93.3% sugar recovery, the highest isomerization rate at the highest concentration ever reported. Indium was present in the single‐crystal catalyst as oxide nanoparticles and boundary framework atoms, and it achieved intelligent cooperation in the production of fructose syrup in methanol by catalyzing isomerization and selective glycosidation, minimizing degradation due to fructose accumulation and eliminating side reactions. This study contributed to the advancement of the industrial practice of chemically catalyzed glucose isomerization.

Methane (CH 4 ) is an attractive energy source and important greenhouse gas. Therefore, from the economic and environmental point of view, scientists are working hard to activate and convert CH 4 into various products or less harmful gas at low-temperature. Although the inert nature of C-H bonds requires high dissociation energy at high temperatures, the efforts of researchers have demonstrated the feasibility of catalysts to activate CH 4 at low temperatures. In this review, the efficient catalysts designed to reduce the CH 4 oxidation temperature and improve conversion efficiencies are described. First, noble metals and transition metal-based catalysts are summarized for activating CH 4 in temperatures ranging from 50 to 500 °C. After that, the partial oxidation of CH 4 at relatively low temperatures, including thermocatalysis in the liquid phase, photocatalysis, electrocatalysis, and nonthermal plasma technologies, is briefly discussed. Finally, the challenges and perspectives are presented to provide a systematic guideline for designing and synthesizing the highly efficient catalysts in the complete/partial oxidation of CH 4 at low temperatures.

“…In the past years, several non-centrosymmetric 2D materials exhibiting both electrical/optical anisotropy and nonlinearity have been reported, such as GeSe [17] and NbOI 2 . [18] However, there are several challenges that hinder the applications of these materials in the field of optoelectronic devices, such as inadequate air stability, low optoelectronic anisotropy ratio (always <3) [19] and low nonlinear optical susceptibility.…”

Integrating anisotropy and nonlinearity of physical properties in 2D materials is of great importance to the progress of nanoelectronic, nanophotonic, and nano‐optoelectronic applications. In this work, Nb3SeI7, a newly discovered ternary layered material with non‐centrosymmetric lattices, is introduced, which exhibits strong second harmonic generation (SHG), in‐plane anisotropic electricity, and light absorption. Symmetry breaking of 2D Nb3SeI7 induced by the polar off‐center displacement of niobium leads to a high nonlinear optical response with a second‐order susceptibility of 6.71 pm V−1 and a high anisotropic factor of photoresponsivity up to 4.6, which are higher than most of the 2D materials. These properties of 2D Nb3SeI7 create new possibilities for chip‐integrated nonlinear optics devices and future‐proof polarization‐sensitive optoelectronic systems.
