Scale-up of high entropy sulfides for thermal catalysis and tribology

Objetivo

“ScaleHES” develops the first scaled synthesis for high entropy sulfides (HES, (Me1…Me5)xSy) to overcome the single‑principal-element limitations of conventional sulfides and unlock entropy‑engineered, multi‑functional sulfide performance in sustainability‑relevant markets. We will scale batch synthesis from <1 g to >100 g via two complementary routes: a high‑temperature solid‑state process that yields highly crystalline bulk HES for subsequent nanostructuring and a low‑temperature wet-chemistry route that will produce intrinsically nanostructured HES nanoparticles. The scaled HES materials will be validated in two high‑value use cases: First, thermal CO2‑to‑methanol catalysis will target increased methanol selectivity and increased activity versus MoS2, building on compelling preliminary selectivity data. Second, solid lubrication under harsh conditions will leverage random elemental occupancy in layered HES to suppress lattice lock‑in, reducing friction and wear and extending operating windows versus conventional sulfide benchmarks. Success will be measured by reproducible >100 g batches, quantitative performance gains in catalysis and tribology, and consolidation of a defensible IP portfolio on scalable synthesis routes and composition families to enable spin‑off foundation after the ERC PoC. The opportunity is timely: HES remain completely absent from commercial supply despite a sizable specialty sulfide market and with minimal nascent IP, creating a first‑mover window. A staged exploitation strategy positions “ScaleHES” to catalyze industrial uptake. By delivering scale, application performance, and IP, “ScaleHES” will establish HES as an enabling materials platform for greener catalysis, more efficient tribology, and future applications.
