How a Titanium Crystal-deficient Overlayer Improves the Efficiency of Solar Energy to Hydrogen Conversion

■ Engineering & Technology / How a Titanium Crystal-deficient Overlayer Improves the Efficiency of Solar Energy to Hydrogen Conversion New study unveils the role of a titanium crystal-deficient overlayer in improving the properties and efficiency of solar energy conversion to hydrogen. Conventionally used photocatalysts and photoelectrochemical cells suffer from poor conductivity and can only store limited amounts of separated charge carriers. In order to circumvent this drawback, a new semiconductor electrode or photocatalyst made of a thin “crystal-deficient” titanium oxide (TiO2) overlayer surrounded by anatase crystal, a variant of TiO2, had been proposed earlier. This ingenious structure triggered many follow-up studies and is considered a … Continue reading How a Titanium Crystal-deficient Overlayer Improves the Efficiency of Solar Energy to Hydrogen ConversionRead More →
