In an effort to reduce the platinum group metal (PGM) content in proton exchange membrane fuel cells (PEMFCs) a value comparable with conventional vehicles, concerted global over past decade has been made by cell community develop high activity oxygen reduction reaction (ORR) catalysts. However, as PGM loadings electrode assemblies (MEAs) decrease below 0.125 mg/cm2, it become clear that ORR mass is just one of challenges which must be overcome. At anode, appears kinetic limitation may have...
Current protocols for synthesizing monodisperse platinum (Pt) nanoparticles typically involve the use of hydrocarbon molecules as surface-capping ligands. Using Pt catalysts oxygen reduction reaction (ORR), however, these ligands must be removed to expose surface sites. Here, highly durable ORR are realized without ligand removal; instead, native converted into ultrathin, conformal graphitic shells by simple thermal annealing. Strikingly, annealing temperature is a critical factor dictating...
ABSTRACT Binders play a critical role in the preparation and operation of electrodes lithium‐ion batteries (LIBs). Developing new binding materials with high affinity to Li ions resistance higher voltages was desirable for practical applications LIBs. In this work, soluble polyimide binder (PI) random copolymerized rigid‐flexible segments were synthesized evaluated as cathode typical lithium iron phosphate material terms cycling performances, rate capability, electrochemical impedance. By...
Rapid screening of Pt/C PEMFC catalysts through RDE methods to accelerate the development with an optimal spatial distribution Pt within carbon support.
Anode reversal occurs in proton exchange membrane fuel cells (PEMFCs) when one or several electrode assemblies (MEAs) a stack experience global hydrogen starvation, causing the anode potential to reach values > 1.5 V leading rapid carbon corrosion and eventually catastrophic failure of MEA. To mitigate this, common solution has been add an anti-reversal catalyst (ARC) into which can promote water oxidation favor corrosion. The most accelerated stress test (AST) for evaluating new ARCs...
Synthetic single-wall carbon nanotubes (SWCNTs) contain various chiralities, which can be sorted by DNA. However, finding DNA sequences for this purpose mainly relies on trial-and-error methods. Predicting the right to sort SWCNTs remains a substantial challenge. Moreover, it is even more daunting predict sorting with target chirality. Here, we present deep-learning (DL) enhanced strategy accurate prediction of capable target-chirality nanotubes. We first experimentally screened 216 using...
ABSTRACT Upcycling the wasted polyamide 6 (PA6) to its monomer caprolactam via depolymerization is a promising way build resource cycling and alleviate environmental pollution. High efficient catalyst for PA6 desirable crucial. Herein, sulfonated Fe‐MOF was designed performed as solid acid first time. Results showed that 100% conversion of water‐soluble liquid products can be achieved at temperatures 250°C after only 1‐h reaction. LC/MS results indicated were mainly composed their oligomers....

Abstract A series of (Pr, Ce)‐ZrSiO 4 ceramic pigments were synthesized and characterized using XRD , SEM EDS XPS XRF colorimeter, a UV ‐ VIS NIR spectrometer. The prepared mainly composed the zircon phase well crystallized. Only specific amount Pr was incorporated into ZrSiO lattice. Compared with Pr, Ce almost completely lattice homogeneously distributed within pigment particles. dopant reduced dissolved in thus caused b * values samples to decrease slightly. Meanwhile, presence induced an...
