The water-gas shift (WGS) reaction (where carbon monoxide plus water yields dihydrogen
and carbon dioxide) is an essential process for hydrogen generation and carbon monoxide …

Preparation of single atom catalysts (SACs) is of broad interest to materials scientists and
chemists but remains a formidable challenge. Herein, we develop an efficient approach to …

Different from isolated metal atoms and large metal nanoparticles (NPs), supported metal
clusters (SMCs) possess distinct geometric and electronic structures and thus exhibit …

A large family of heterogeneous catalytic reactions require active sites with more than one
metal atom, that is, an ensemble of metal atoms. The ensemble requirement, which refers to …

Tumors are not only aggregates of malignant cells but also well-organized complex
ecosystems. The immunological components within tumors, termed the tumor immune …

Solar energy provides an alternative, sustainable, and clean source of energy to meet the
global energy demands without extra carbon emissions. However, the utilization efficiency of …

Methanol–water reforming is a promising solution for H 2 production/transportation in
stationary and mobile hydrogen applications. Developing inexpensive catalysts with sufficiently …

A titanium carbide (Ti 3 C 2 T x ) MXene is employed as an efficient solid support to host a
nitrogen (N) and sulfur (S) coordinated ruthenium single atom (Ru SA ) catalyst, which …

Cervical cancer is one of the most common cancers threatening women's health, and the
persistent infection of high-risk human papillomavirus (HPV) is closely related to the …
