Low-temperature CO2 hydrogenation might have sounded almost paradoxical until a recent study made it possible. Researchers have designed new catalysts that can transform the greenhouse gas into methanol at temperatures ranging from room temperature to 200° C, whereas most catalysts can operate only at or above 250° C. The research is published in the journal Nature Chemistry.
