A heterogeneous catalyst prepared in water is, clearly, a cleaner one that leads to cleaner syntheses. La 2 CuO 4 formed in supercritical water is produced more quickly, has a higher surface area, and a greater activity towards CO oxidation than the corresponding materials prepared by “traditional” ceramic synthesis. The method could feasibly be scaled up or applied to other solid‐state products.
