Rare earth oxide based electrocatalysts: synthesis, properties and applications

“…Furthermore, Tang et al also optimized the oxygen electrocatalytic activity of Fe/NC by adding the element dysprosium (Dy) (denoted as Dy 2 O 3 -Fe/NC). 225 The prepared catalyst showed excellent ORR/OER activity at 0.1 M KOH, with an E 1/2 of 0.914 V and an overpotential of 396 mV (current density of 10 mA cm À2 ). The excellent bifunctional electrocatalytic activity is due to the close cooperation between Fe and Dy, as well as the newly formed active site in FeN x -Dy 2 O 3 .…”

A Shish-Kebab Superstructure Film for Personal Radiative Cooling

“…With the aggravation of global warming, heat stress becomes an increasingly serious problem, which could cause physical discomfort to people, increase the risk of disease, and seriously threaten human health. , Rather than cooling the human body directly, buildings around people are cooled first in the traditional cooling process, which will inevitably generate energy waste. − Therefore, the concept of personal thermal management (PTM) has been proposed. − It focuses only on heating and cooling the human body and the local environment, thus reducing unnecessary energy consumption to the surrounding building. − In a normal environment, the body skin, which is approximately 34 °C, emits mid-infrared (MIR) radiation with a wavelength of 7 to 14 μm to the outside. This accounts for nearly 60% of the human body’s heat loss (Figure a) .…”
