Transformative 3D Printing of Carbon‐metal Nanocomposites as Catalytic Joule Heaters for Enhanced Ammonia Decomposition

Advanced Science, Journal Year: 2025, Volume and Issue: unknown

Published: April 27, 2025

Abstract Electrified thermal chemical synthesis plays a critical role in reducing energy consumption and enabling the industrial decarbonization. While Joule heating offers promising alternative to gas‐burning furnace systems by directly substrates via renewable supply, most approaches can only heat reactor, not catalytic sites. This limitation stems from lack of methods on‐demand create heaters containing situ loaded nanoparticles. work introduces scalable platform for producing carbonaceous embedded with nanoparticles 3D‐printed polypropylene precursors, prepared through crosslinking, metal nitration immersion, pyrolysis steps. Specifically, sulfonate groups on crosslinked PP bind ions, yielding well‐dispersed, nanosized particles within carbon structure that maintains macroscopic dimensional accuracy throughout manufacturing. The approach is modular, allowing control over particle size composition. Structured nickel demonstrates efficient heating, high activity, significantly reduced activation ammonia decomposition. provides an innovative material manufacturing produce structured, catalytically active decarbonization production.
