Transition metal phosphides are a new class of materials generating interest as alternative negative electrodes in lithium-ion batteries. However, metal phosphide syntheses remain underdeveloped in terms of simultaneous control over phase composition and 3D nanostructure. Herein, M13 bacteriophage is employed as a biological scaffold to develop 3D nickel phosphide nanofoams with control over a range of phase compositions and structural elements. Virus-templated Ni P nanofoams are then integrated as thin-film negative electrodes in lithium-ion microbatteries, demonstrating a discharge capacity of 677 mAh g (677 mAh cm ) and an 80% capacity retention over more than 100 cycles. This strong electrochemical performance is attributed to the virus-templated, nanostructured morphology, which remains electronically conductive throughout cycling, thereby sidestepping the need for conductive additives. When accounting for the mass of additional binder materials, virus-templated Ni P nanofoams demonstrate the highest practical capacity reported thus far for Ni P electrodes. Looking forward, this synthesis method is generalizable and can enable precise control over the 3D nanostructure and phase composition in other metal phosphides, such as cobalt and copper.

Nickel phosphide (NiP) is an emerging efficient catalyst for the hydrogen evolution and water splitting. Herein, we report that NiP is also a promising catalyst for enhancing electrochemical dechlorin...
Transition metal phosphide catalysts such as nickel phosphide (NiP) have shown excellent activities for the hydrogen evolution reaction, but they have primarily been studied in strongly acidic or alka...
We report a new family of nickel phosphinidene molecular clusters synthesized from the reaction of bis(1,5-cyclooctadiene)nickel(0) (Ni(COD)2) with organocyclophosphine and trialkylphosphine. We find ...
We studied thin-film and free-standing Mg-doped GaN using multi-frequency electron paramagnetic resonance (EPR) at 3-3.5 K and 9.4-130 GHz. Free-standing samples exhibit a highly anisotropic intensity...
Heterostructures with abundant phase boundaries are compelling for surface-mediated electrochemical applications. However, rational design of such bifunctional electrocatalysts for efficient hydrogen ...
There is little evidence on the effect of a nickel-free diet on gastroesophageal reflux disease (GERD). We hope to determine if a nickel-free diet improves GERD symptoms in patients with a...
