Scalable Solvent-Mediated Nanoarchitectonics of High-Surface-Area Mesoporous Ni₂P₂O₇ for Enhanced Electrochemical Performance in Alkaline Media.

ABSTRACT: Sol-gel synthesis provides a versatile and scalable route for producing high-surface-area materials. Here, we develop a facile sol-gel strategy for mesoporous nickel pyrophosphate (Ni₂P₂O₇) using H₄P₂O₇, nickel nitrate, and Pluronic P123 in butanol- and ethanol-based media. These mixtures form homogeneous sols that gelate and, after drying and calcination at 300 °C, yield powders with surface areas up to 410 m² g^-1. In contrast, methanol systems─and certain ethanol conditions─phase-separate into precipitate and supernatant layers. After calcination, the solution and precipitate fractions produce mesoporous Ni₂P₂O₇, while the supernatant fraction forms Ni₃(PO
