You may have heard that carbon dioxide (CO₂) is a major greenhouse gas responsible for global warming, but did you know? Scientists are researching a remarkable technology——photocatalytic CO₂ reduction——which can m

Photoelectric and photochemical conversion are core areas of energy and materials science, involving processes that convert light energy into electrical or chemical energy. These principles not only drive green technologies such as solar ce

An electrolytic cell is a device that converts electrical energy into chemical energy, widely used in hydrogen production, metal refining, wastewater treatment, and other fields. Its core principle is based on electrolysis: when direct curr

An electrolyzer is a device that converts electrical energy into chemical energy by electrochemically splitting water into hydrogen and oxygen. It is a key technology for achieving green energy conversion. This article will explain the working principle o

Extracting hydrogen from sunlight, this seemingly sci-fi technology is quietly transforming our energy future. Imagine producing clean hydrogen fuel using only sunlight and water—this is not only a miracle of nature but also a brilliant achievement of hum

Small materials, yet the key to converting sunlight into hydrogen energy
In the "feast" of water splitting for hydrogen production that transforms sunlight and water into clean hydrogen energy, photocatalysts play an indispensable role as the "matchma
