Abstract The previous studies mainly focused on improving microwave absorbing (MA) performances of MA materials. Even so, these designed materials were very difficult to be employed in complex and changing environments owing their single-functionalities. Herein, a combined Prussian blue analogues derived catalytical chemical vapor deposition strategy was proposed produce hierarchical cubic sea urchin-like yolk–shell CoNi@N-doped carbon (NC)-CoNi@carbon nanotubes (CNTs) mixed-dimensional multicomponent nanocomposites (MCNCs), which composed zero-dimensional CoNi nanoparticles, three-dimensional NC nanocubes one-dimensional CNTs. Because good impedance matching attenuation characteristics, the CoNi@NC-CoNi@CNTs MCNCs exhibited excellent performances, achieved minimum reflection loss ( RL min ) −71.70 dB at 2.78 mm Radar Cross section value −53.23 m 2 . More importantly, acquired results demonstrated that presented photothermal, antimicrobial anti-corrosion properties structure, highlighting potential multifunctional applications. It could seen this finding not only generalizable route magnetic NC-CNTs-based MCNCs, but also provided an effective develop improve environmental adaptabilities.

Based on their excellent stability, high carrier mobility, and wide photoresponse range, composites formed by embedding perovskite quantum dots (PQDs) into metal-organic frameworks (PQDs@MOF) show great development potential in the field of photocatalysis, including toxic hexavalent chromium (Cr6+) degradation, CO2 reduction, H2 production, etc. However, rapid recombination photogenerated carriers is still a major obstacle to improvement photocatalytic performance, internal mechanism photocatalysis unclear. In this work, we construct novel double heterojunction photocatalyst encapsulating CsPbBr3 PQDs Zr-based (UiO-67) loading additional hole-acceptor pentylenetetrazol (PTZ). Spontaneous photoinduced charge-transfer separation between interfaces are confirmed time-resolved photoluminescence transient absorption spectroscopy. Furthermore, compared with pure UiO-67, photoactivity PQDs@UiO-67@PTZ increased 3-fold due long-lived charge-separated state. Our findings provide new guideline for design PQDs@MOF-based photocatalysts outstanding activity.
