“…Unfortunately, due to the weak interaction between the metal particles and the carbon base, the metal nanoparticles usually detach from the carbon base or conglomerate during catalytic reactions. Although the stability and acid resistance of catalysts have been improved by numerous strategies such as the template method, − chemical vapor deposition, , and metal organic framework mediated method, through the synthesis of metal incorporated carbon structures, rigorous or tedious synthetic processes still limit the widespread application of the metal incorporated carbon catalyst. In addition, excessive pursuit of stability can also affect catalyst activity.…”

Most of the catalytic hydrogenation reactions take place under high temperature, high pressure, and high corrosion, which poses a challenge to the activity and stability of hydrogenation catalysts. Herein, an acid resistant and strawberry-like metal–carbon sphere (M/SCS) as a robust hydrogenation catalyst was synthesized by a one-step method. Self-assembled metal nanoparticles gather and are embedded on the surface of the carbon sphere prepared by the carbonization of phenolic resin. By means of the surrounding carbon layer, the acid resistant capability is orders of magnitude intensified compared to traditional commercial catalysts. Over 91.5% and 100% metals of Pd/SCS7 and Pt/SCS7 remain as the catalyst in hydrochloric acid (36–38 wt %), while less than 44.6% and 37.5% metals remain of commercial Pd/AC and Pt/AC. In addition, the sizes are controlled in the range of 11 to 18 nm for metal particles and 400 to 1600 nm for carbon spheres by adjusting the conditions of phenolic aldehyde condensation. N atoms anchored on the carbon spheres with high dispersion can improve electron density on metal particles. M/SCS exhibits both excellent stability and high catalytic performance in the hydrogenation reactions.

Protein phosphorylation regulates and controls protein activity and function, which is the most basic and important part in organisms’ lives. However, the low abundance and ionization inhibition of phosphopeptides make it difficult to understand and analyze the protein phosphorylation mechanism. In this study, we synthesize a core‐shell structured magnetic Ti4+‐based immobilized metal ion affinity chromatography material for highly selective enrichment of phosphopeptides. The introduction of negatively charged carbon layer increases the specific surface area and avoids loss of the immobilized Ti4+ during sample loading and washing. The synthesized magnetic superhydrophilic extractant is employed to separate and enrich phosphopeptides from standard protein digests coupled with MALDI‐TOF MS. It exhibits excellent enrichment performance of high selectivity (1 : 2000 molar ratio of β‐casein and BSA), sensitivity (low detection limit of 4 fmol) and preferable reusability (at least 12 times) as well as excellent adsorption capacity of 142.5 mg ⋅ g−1 and high recovery rate of 85.6 %. Moreover, sixteen phosphopeptides and four endogenous phosphopeptides can be accurately identified from non‐fat milk and human serum, further indicating the great potential and bright application in phosphoproteomics analysis.
