Hunting out hidden hydrogen: Novel holey nanosheets for detecting hydrogen gas leaks

Posted On: 03/19/21

While detectors for H2 leaks are available, they require high temperatures to operate, making them expensive, short-lived, and dangerous to use for detection of an explosive or flammable gas. A team of scientists from Incheon National University, Korea, have come up with a novel room temperature H2 sensor design that makes use of nanometer-thin 2-D sheets of zinc oxide filled with nanometer-size holes, aptly named 'holey 2-D nanosheets,' that can potentially revolutionize gas sensing performance in the future.
