Copper Chromite (CuCr₂O₄) — Catalyst Grade Cu–Cr Oxide for Hydrogenation Systems
Cu–Cr mixed oxide supplied as a catalyst component or precursor, designed for reduction activation and structured catalytic formulations.
Introduction
Copper chromite (CuCr₂O₄) catalyst grade is a copper–chromium mixed oxide supplied for use as an
active catalytic component or precursor in industrial hydrogenation and reduction systems.
This material is not a finished catalyst. It is intended for formulation with supports, binders,
and shaping processes, followed by controlled reduction activation (typically hydrogen) to generate
the catalytically active Cu–Cr surface.
Typical applications include aldehyde-to-alcohol hydrogenation, ester hydrogenation, and Cu–Cr based catalytic systems
where thermal stability, controlled reducibility, and mechanical robustness are required.
Copper chromite (CuCr₂O₄) is a Cu–Cr mixed oxide supplied as a catalyst component or precursor.
After formulation and reduction activation, it forms catalytically active copper species
stabilized by chromium oxide phases.
Chemical composition: Cu–Cr mixed oxide (primary phase: CuCr₂O₄)

(≤ ~480 °C typical; atmosphere dependent)
Redox behavior: Reducible Cu²⁺ → Cu⁰/Cu⁺ under hydrogen activation
Mechanical robustness: Suitable for pelletization, extrusion, or supported systems
Functional Role in Catalysis
Acts as an active catalytic component after reduction activation
Provides Cu active sites stabilized by Cr-oxide matrix
Supports long-term thermal and mechanical stability
Explicit Boundary Conditions
Not supplied as a ready-to-use catalyst
Requires formulation with supports/binders
Requires reduction activation before catalytic use
Final performance depends on shaping, porosity, and operating conditions
FAQ
Is this a finished catalyst? No. It is a catalyst-grade component or precursor.
Does it require activation? Yes. Typically reduced under hydrogen.
What reactions is it used for? Hydrogenation and Cu–Cr based reduction systems.
Can it be supported? Yes. Commonly formulated with inorganic supports.
Is it electrically conductive? Conductivity is not a functional design target for catalytic use.
What data is available? TDS, SDS, CoA, phase ID, and redox behavior summaries.
Is chromium leachable? Leachability depends on formulation and operating environment.
Can it replace Raney copper? No. It serves different stability and structural roles.
Data source: Internal QC and typical catalyst-grade specifications.
Final performance must be validated in the customer’s catalytic system.
Definition: Copper chromite (CuCr₂O₄) is a Cu–Cr mixed oxide used as a catalyst component or precursor that typically requires reduction activation to generate catalytically active copper sites stabilized by chromium oxide phases.
