Thanks to nitrogen introduced into the layered carbon framework of graphite, chemical reactivity atoms was increased. N-doped graphitic catalysts generate reactive oxygen species and display excellent activity for hydrocarbon activation even at room temperature. As a service our authors readers, this journal provides supporting information supplied by authors. Such materials are peer reviewed may be re-organized online delivery, but not copy-edited or typeset. Technical support issues...
Reduced graphene oxide was used as a catalyst for reduction of nitrobenzene at room temperature. High catalytic activity and stability were exhibited in circular experiments. The procedure situ monitored by NMR N-phenylhydroxylamine proved to be the intermediate this reaction.
We report an efficient, highly selective, and low temperature graphene-catalyzed reaction process for one-step oxidation of benzene to phenol with hydrogen peroxide as the oxidant. The chemically converted graphene (CCG) from small graphite was used catalyst. conversion reaches 18%, being sole product. catalyst reusable very stable. By XPS, C K-edge X-ray absorption spectra, benzene-TPD, kinetic measurements, it concluded that moderate H2O2 activation rate, good adsorption ability, balanced...
Because of limited framework stability tolerance, de novo synthesis sulfonated covalent organic frameworks (COFs) remains challenging and unexplored. Herein, a two-dimensional crystalline COF, termed TFP-DABA, was synthesized directly from 1,3,5-triformylphloroglucinol 2,5-diaminobenzenesulfonic acid through previously reported Schiff base condensation reaction, followed by irreversible enol-to-keto tautomerization, which strengthened its structural stability. TFP-DABA is highly efficient...
Single-atom catalysts (SACs) have attracted much attention due to their outstanding catalytic performance in heterogeneous catalysis.

The fabricated presented dispersities, leading distinguishing performance. optimized Co1@NC-(SBA)...
Monodisperse bimetallic Pd-Cu nanoparticles with controllable size and composition were synthesized by a one-step multiphase ethylene glycol (EG) method. Adjusting the stoichiometric ratio of Pd Cu precursors afforded different compositions, such as Pd(85)-Cu(15), Pd(56)-Cu(44), Pd(39)-Cu(61). The separated from solution mixture extraction non-polar solvents, n-hexane. narrow size-distribution obtained without need for size-selection process. Capping ligands that bound to surface particles...
The direct synthesis of metal–organic frameworks (MOFs) with strong Brønsted acidity is challenging because the functional groups exhibiting (e.g., sulfonic acid groups) often jeopardize framework integrity. Herein, we report two hierarchically porous MOFs named NUS-6 composed either zirconium (Zr) or hafnium (Hf) clusters high stability and acidity. Via modulated hydrothermal (MHT) synthesis, these can be easily synthesized at a low temperature (80 °C) throughput. They exhibit BET surface...
