Abstract Platinum is one of the best‐performing catalysts for hydrogen evolution reaction (HER). However, high cost and scarcity severely hinder large‐scale application Pt electrocatalysts. Constructing highly dispersed ultrasmall entities thereby a very effective strategy to increase utilization mass activities, reduce costs. Herein, composed mixture single atoms, clusters, nanoparticles are synthesized on mesoporous N‐doped carbon nanospheres. The presence demonstrated by combining among...
Abstract Vapor‐based deposition techniques are emerging approaches for the design of carbon‐supported metal powder electrocatalysts with tailored catalyst entities, sizes, and dispersions. Herein, a pulsed CVD (Pt‐pCVD) approach is employed to deposit different Pt entities on mesoporous N‐doped carbon (MPNC) nanospheres high‐performance hydrogen evolution reaction (HER) electrocatalysts. The influence consecutive precursor pulse number (50‐250) temperature (225–300 °C) investigated. Pt‐pCVD...
Molecular solar thermal energy storage (MOST) systems are rapidly becoming a feasible alternative to and net-zero carbon emission heating. MOST involve single photoisomerization pair that incorporates light absorption, storage, heat release processes in one recurring cycle. Despite significant recent advancements the field, catalytic back-reaction from remains relatively unexplored. A wide range of applications is possible, contingent on densities specific photoisomers. Here, we report...
Abstract The rational design of carbon‐based electrode materials plays an important role in improving the electrochemical properties both, energy storage and conversion electrodes devices. For most applications, well‐defined easily processable porous with controlled particle morphology (ideally spherical), size, intraparticle pore size are desired. Here, a hard‐templating synthesis toolbox is reported for highly‐monodisperse meso‐ macroporous N‐doped carbon nanospheres (MPNCs) as versatile...
As the global deployment of renewable technologies accelerate, finding efficient ways to store energy will aid in responding shifting demands. A prospective option not only harvesting solar but also emission‐free heating is MOlecular Solar Thermal (MOST) storage. central part MOST applications develop methods release stored energy. Herein, Quadricyclane (QC)‐to‐Norbornadiene catalyzed back reaction explored a specially designed packed‐bed reactor. Four distinctly sized and purposely...
Considering the global and growing technological demand for platinum, increasing its utilization is key in context of green hydrogen production by proton exchange membrane water electrolysis. An effective strategy to increase Platinum Pt/C evolution electrocatalysts Pt dispersion on conductive carbon support reduce nanoparticle size down clusters or even single sites. In that 3D porous N-doped supports helpful form stabilize highly dispersed species achieve high mass activities. here we...
