Novel, Lead-Free Double Perovskites as Potential Photocatalysts for Solar Water Splitting (IMAGE)
Caption
Solar energy is clean and abundant, but when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen, which can then be recombined in a fuel cell to release energy. Now, a new class of materials -- halide double perovskites -- may have just the right properties to split water, according to research in Applied Physics Letters.
