It is a great challenge to explore cheap, abundant and eco-friendly electrocatalysts for hydrogen evolution reaction (HER).

A NiMoS₄ nanoarray on Ti mesh (NiMoS₄/Ti), developed via topotactic hydrothermal conversion from its Ni(OH)₂ nanoarray (Ni(OH)₂/Ti), drives hydrogen-evolution current densities of 10 and 50 mA cm⁻² at overpotentials of 194 and 263 mV in 0.1 M KOH, respectively.

Two-dimensional 1T′ phase MoS₂ that was intercalated with a series of alkylated p-phenylenediamines exhibits excellent catalytic activity toward hydrogen evolution reaction, supported by first-principles calculations.

A novel Zr-MOF based smart adsorbent was fabricated for the simultaneous detection and removal of organophosphorus pesticides in wastewater.

An ultrastable Zn-MOF shows recyclable and multi-responsive sensing for Cr(iii), Cr(vi) and 4-nitrophenol in an aqueous system with high selectivity and sensitivity.

A vacancy induced 2D/2D Z-scheme bifunctional photocatalyst La₂Ti₂O₇/g-C₃N₄ was constructed and applied for enhanced solar-to-energy conversion.

Arrhenius plots of the total conductivity in (1 and 3) dry and (2 and 4) wet air of two Yb₆MoO₁₂polymorphs: (1 and 2) bixbyite (Ia3̄(206)) Yb₆MoO₁₂and (3 and 4) rhombohedral (R3̄) Yb₆MoO₁₂; Yb₆MoO₁₂rhombohedral (R3̄) → Yb₆MoO₁₂bixbyite (Ia3̄(206)) atT∼ 1600 °C.

In-site grown 3D flower-like Ni–Fe layered double hydroxides and carbon black nanoparticles were hydrothermally hybridized and showed great potential as an alternative high-rate alkaline cathode.

Ni₂P serves as a highly stable non-noble-metal co-catalyst to efficiently promote H₂generation of g-C₃N₄.
