Layer-by-Layer Assembly of Reduced Graphene Oxide and MXene Nanosheets for Wire-Shaped Flexible Supercapacitors

Junyeong Yun et al.

Summary: This study demonstrates the use of the layer-by-layer (LbL) assembly technique to create wire-shaped supercapacitors (WSCs) with enhanced capacitance, energy density, and power density. The WSCs consist of alternating layers of positively charged reduced graphene oxide functionalized with poly(diallyldimethylammonium chloride) and negatively charged Ti3C2Tx MXene nanosheets conformally deposited on activated carbon yarns. The LbL coatings on carbon yarns show promise as linear energy storage devices for fibrous electronics.

Gd-induced electronic structure engineering of a NiFe-layered double hydroxide for efficient oxygen evolution

Meng Li et al.

Summary: Rare earth elements have recently attracted attention as effective promoters in electrocatalysis due to their partially filled 4f orbitals. A new type of Gd-doped hybrid electrocatalyst, Gd-NiFe-LDH@CC, was designed and developed through a one-step hydrothermal approach. The Gd doping enhanced the OER performance by optimizing the electronic structure of NiFe-LDH, increasing oxygen vacancies, and improving binding strength of intermediate species such as HOO*. Additionally, the Gd-NiFe-LDH@CC exhibited superior electrocatalytic activity and stability for the OER compared to NiFe-LDH@CC and commercial RuO2.
