One-step removal of alkynes and propadiene from cracking gases using a multi-functional molecular separator
Separating mixtures of hydrocarbons of low molecular weight is desirable but challenging. Here, the authors report a porous material with responsive and self-adaptive properties that enables one-step removal of alkynes and propadiene from cracking gases.

A tailored multi-functional catalyst for ultra-efficient styrene production under a cyclic redox scheme
Styrene is an important commodity chemical that is highly energy and CO2 intensive to produce. Here, authors report a redox-oxidative dehydrogenation scheme and a tailored core-shell redox catalyst to convert ethylbenzene to styrene with up to 91.4% single-pass yield and 82% energy savings.

Site-dependent reactivity of MoS2 nanoparticles in hydrodesulfurization of thiophene
MoS2 nanoparticles catalyze the extraction of heteroatom S in hydrocarbons by adsorption onto S vacancies. Here, the authors show that S vacancy properties are highly site sensitive and that adsorption of thiophene leads to self-generation of a more open double vacancy site.
