A review of the fundamental principles that allow for intelligent design and synthesis non-precious metal nanostructured electrocatalysts ADAFCs.
Recently reported ruthenium (Ru)-based catalysts for the oxygen evolution reaction (OER) falling in Ru metal and compound subclasses are summarized with special emphasis being given to a discussion of activity/stability-enhancing strategies.
This study reports on the valorisation of marula nutshell waste into a valuable electrode material for supercapacitors. Marula waste, brown hard residue from fruits was valorised nitrogen-doped activated carbon (N-ACs) by KOH treatment and using melamine as nitrogen source. The microporous mesoporous nature N-ACs exhibited high surface area 1427 m² g−1 pore volume 0.31 cm3 g−1. Three measurements were done in 6 M 2.5 KNO3 aqueous electrolytes, to examine materials alkaline neutral medium....
The supercapacitive properties of nickel(II) tetraaminophthalocyanine (NiTAPc)/multi-walled carbon nanotube (MWCNT) nanocomposite films have been interrogated for the first time and found to possess a maximum specific capacitance 981 ± 57 F g−1 (200 12 mF cm−2), power density 700 1 Wkg−1, energy 134 8 Wh kg−1 excellent stability over 1500 charge-discharge continuous cycling. Impedimetric study proves that most stored MWCNT-NiTAPc can be accessible at high frequency (720 Hz). When compared...
In this review, we describe and discuss the developments in use of metalloporphyrins metallophthalocyanines as catalysts for oxygen reduction aqueous electrolytes. The main goal most researchers field has been to design which can achieve facile by four-electron transfer pathway at lowest overpotential possible. With mind, primary objective review was bring light research frontiers uncovering important milestones towards synthesis promising N 4 -metallomacrocyclic accomplish oxygen, and,...
The LiMn1.5Ni0.5O4 spinel is an important lithium ion battery cathode material that has continued to receive major research attention because of its high operating voltage (∼4.8 V). This study interrogates the impact microwave irradiation on Mn3+ concentration and electrochemistry spinel. It shown capable tuning content for enhanced electrochemical performance (high capacity, capacity retention, excellent rate capability, fast Li+ insertion/extraction kinetics). finding promises...
Flower-like MoS<sub>2</sub>modified with carbon nanospheres (CNS) displays energy-storage capability when used as an aqueous symmetric pseudocapacitor.
The energy storage performance of one the lightest-known MXenes, Ti2CTx (MX) combined with carbon nanospheres (CNS) has been investigated as a symmetric electrode system in an aqueous electrolyte (1 M Li2SO4). properties were interrogated using cyclic voltammetry (CV), galvanostatic cycling potential limitation (GCPL), electrochemical impedance spectroscopy (EIS) and voltage-holding tests. material (MX/CNS) demonstrated higher specific capacity compared to each individual components. was...
FeCo@Fe@Pd nanocatalyst exhibits excellent selectivity towards the oxidation of EG and glycerol in ADAFCs.
The carbon onion/birnessite-type manganese oxide nanohybrid symmetric pseudocapacitor exhibits excellent capacitive properties compared to the conventional onion supercapacitor.
We present a facile method for the rational design of highly exfoliated two-dimensional Ti 3 C 2 T x nanosheets (T = O, OH, and F) doped with Cu (Cu/Ti ) electrochemical CO reduction to formic acid at low content ∼1 wt%.
Fractal Pt-based materials with hierarchical structures and high self-similarity have attracted more attention due to their bioinspiring maximum optimization of energy utilization mass transfer. However, high-efficiency design the mass- electron-transfer still remains be a great challenge. Herein, fractal PtPdCu hollow sponges (denoted as PtPdCu-HS) facilitating both directed are presented. Such transfer effects greatly promote electrocatalytic activity, regarded 3.9 times 7.3 specific...
