On-chip micro-supercapacitors (MSCs), as promising power candidates for microdevices, typically exhibit high density, large charge/discharge rates, and long cycling lifetimes. However, most reported MSCs, the unsatisfactory areal energy density (<10 µWh cm-2 ) still hinders their practical applications. Herein, a new-type Zn-ion hybrid MSC with ultrahigh long-term durability is demonstrated. Benefiting from fast ion adsorption/desorption on capacitor-type activated-carbon cathode reversible...

MXene (e.g., Ti3 C2 ) represents an important class of two-dimensional (2D) materials owing to its unique metallic conductivity and tunable surface chemistry. However, the mainstream synthetic methods rely on chemical etching MAX powders AlC2 using hazardous HF or alike, leading sheets with fluorine termination poor ambient stability in colloidal dispersions. Here, we demonstrate a fluoride-free, iodine (I2 assisted route for preparing 2D (Ti3 Tx , T=O, OH) oxygen-rich terminal groups intact...

Advanced supercapacitor electrodes require the development of materials with dense redox sites embedded into conductive and porous skeletons. Two-dimensional (2D) conjugated metal–organic frameworks (c-MOFs) are attractive electrode due to their high intrinsic electrical conductivities, large specific surface areas, quasi-one-dimensional aligned pore arrays. However, reported 2D c-MOFs still suffer from unsatisfying capacitances narrow potential windows because redox-inactive building blocks...
The synthesis of novel two-dimensional (2D) materials displaying an unprecedented composition and structure via the exfoliation layered systems provides access to uncharted properties. For application in optoelectronics, a vast majority exfoliated 2D semiconductors possess n-type or more seldom ambipolar characteristics. shortage p-type enormously hinders extensive engineering devices for complementary metal oxide (CMOSs) beyond CMOS applications. However, despite recent progress development...
Transition-metal phosphides (TMPs) have emerged as a fascinating class of narrow-gap semiconductors and electrocatalysts. However, they are intrinsic nonlayered materials that cannot be delaminated into two-dimensional (2D) sheets.
