Grove CO2 Temperature Humidity Sensor (SCD30 ...

Carbon dioxide (CO 2) emissions from fossil fuel combustion were almost zero prior to 1750. The United Kingdom was the world’s first industrialized nation – and first fossilfuel CO 2 emitter. In 1751 its (and global) emissions were less than 10 million tonnes – 3600 times less than global emissions today.

Splitting CO2 into CO and O2 by a single catalyst | PNAS

25/9/2012· The metal complex [(tpy)(Mebimpy)RuII(S)]2+ (tpy = 2,2′ : 6′,2′′terpyridine; Mebimpy = 3methyl1pyridylbenzimidazol2ylidene; S = solvent) is a robust, reactive electrocatalyst toward both water oxidation to oxygen and carbon dioxide reduction to carbon monoxide. Here we describe its use as a single electrocatalyst for CO2 splitting, CO2 → CO + 1/2 O2, in a twocompartment ...


Carbon dioxide sensor Wikipedia

A carbon dioxide sensor or CO 2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors and chemical gas carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes.
