To obtain a recyclable and environmentally friendly solid catalyst with excellent catalytic properties selectivity for 4-nitrophenol (4-NP) hydrogenation, herein, covalent organic frameworks (COFs) are used as the support. Tiny PdCo alloy particles confined in pores of COFs to acquire PdCo/COFs, an extremely narrow PtCo size distribution (6.28 ± 2.85 nm). The effect Pd+Co loading Pd/Co atomic ratio on behaviors PdCo/COFs 4-NP hydrogenation is explored. as-gained (Pd─1.72, Co─1.23 wt %) exhibits good (conversion─90.5%, 4-aminophenol (4-AP) > 99.0%, conversion─11.0%, TOF─turnover frequency─44.2 min–1) under quite moderate reaction conditions (40 °C, 3.0 MPa hydrogen pressure), have superior stability. Additionally, property better than that monometallic supported catalysts (Pd/COFs or Co/COFs) PdNi/COFs. It can be considered formation beneficial activation 4-NP. analyzed by XRD, XPS, ICP-OES, SEM-EDX, BET, TEM, HRTEM, STEM-EDX elemental analysis, aberration-corrected STEM (AC-STEM), confirming tiny uniformly loaded COFs. samples advantages outstanding stability thus their own desired industrial application potential.

Abstract Hydrogenation of N‐heteroarenes to saturated N‐heterocycles is an important reaction in organic synthesis. Hydrogen a green reducing reagent and has been widely applied industrial production. The development appropriate catalyst realize hydrogenation at low pressure temperature desired. In this study, we developed cobalt‐based derived from ZIF‐67 that exhibits high activity for N‐heteroarene under 5–20 bar hydrogen, which relatively as compared reported catalytic systems. This nano‐cobalt shows broad substrate scope can be reused without obvious loss.

Hexavalent chromium (Cr(VI)) is mainly detected as a harmful anion in aquatic ecosystems. In this study, novel nanohybrid layered clay composite decorated with polyaniline (PANI) (PANI/LDH@MMt) was successfully synthesized by layer-by-layer assembly strategy and utilized for Cr(VI) removal. Layered double hydroxide (LDH) montmorillonite (MMt) (LDH@MMt) can facilitate elimination through reinforced reduction. Some key experimental parameters were evaluated detail their potential impact on The results illustrated that PANI/LDH@MMt displayed high removal efficiency (>99%) at most appropriate conditions maintained over 95% performance even ionic coexistence natural water environments. Kinetic models, isothermal thermodynamic analyses also employed to explore the behavior PANI/LDH@MMt. Finally, mechanism analysis suggested could be captured electrostatic interaction of -NH-+, -N=+, –OH2+, exchange LDH, reduced Cr(III) -NH-. Subsequently, chelate -N=, −NH−, −OH, complex OH-, immobilized MMt cation exchange. This study presents new insight into reasonable construction highly efficient adsorbents low cost
