This study aims to prepare new nanocomposites consisting of Cr2O3/CaCO3 as a catalyst for improved hydrogen production from NaBH4 methanolysis. The nanocomposite possesses nanoparticles with the compositional formula Cr2−xCaxO3 (x = 0, 0.3, and 0.6). These samples were prepared using sol-gel method, which comprises gelatin fuel. structure composites was studied X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, environmental scanning electron microscopy (ESEM), (XPS). XRD data showed rhombohedral crystallinity samples, average crystal size 25 nm. FTIR measurements represented absorption bands Cr2O3 CaO. ESEM micrographs spherical shape nanoparticles. XPS proved desired oxidation states optical band gap is 3.0 eV, calcium doping causes reduction 2.5 1.3 eV at 15.0 30.0% ratios. methanolysis involved accelerated H2 when catalyst. Furthermore, Cr1.7Ca0.3O3 had highest generation rate, value 12,750 mL/g/min.

The exploitation of highly active, nonprecious metal bifunctional electrodes to facilitate the hydrogen evolution reaction (HER) and oxygen (OER) is essential for water electrolysis produce hydrogen, but performances are still unsatisfactory. Herein, a facile strategy was proposed fabricate three-dimensional (3D) bimetallic phosphide (NiFeP) nanoflower array on self-standing assembled MXene nanosheet film (denoted as NiFeP@MXene) structurally integrated electrode overall splitting. NiFeP@MXene with 3D hierarchical structures can be directly used an without traditional polymer binders, which significantly reduces contact resistance facilitates electron transfer at interface. Meanwhile, interfacial synergistic coupling created between conductive phosphides, favorable catalytic activity. Moreover, addition Fe improves intrinsic activity simultaneously formation flower-like more active sites. Thus, demonstrates excellent in alkaline electrolyte small overpotentials 240 122 mV drive 10 mA cm–2 current density OER HER, respectively, along superior performance compared commercial precious IrO2∥Pt/C catalyst.

The oxygen evolution reaction (OER) is crucial for producing hydrogen through electrochemical water splitting using renewable energy sources. To enhance production efficiency, an electrocatalyst with high efficiency and stability OER necessary. Layered double hydroxides (LDHs) are among the most active electrocatalysts alkaline OER, but LDHs suffer from poor conductivity, potential agglomeration, low intrinsic activity. Herein, sulfur–phosphorus codoping of CoFeLDH/MXene (S,P-CoFeLDH/MXene) nanoarray hybrid was developed a stripped Ti3C2Tx MXene substrate in situ growth strategy codoping. S,P-CoFeLDH/MXene demonstrated remarkable activity against media, overpotential 305 mV at 10 mA cm–2 Tafel slope 39 dec–1. Moreover, decreased by only 1.3% after 2000 CV cycles, surpassing noble metal RuO2 catalyst. This effective introduces idea designed evolution, direct preparation method lays groundwork its broad application.
