comando \cite não funciona

Eu estava usando biblatexsem tantos problemas. Mas de repente, quando eu quis usar \cite, nenhuma fonte bibliográfica apareceu. Aqui está um MWE:

 \documentclass[a4paper,openright,10pt]{book}
 \usepackage[utf8]{inputenc}
 \usepackage[spanish, es-tabla]{babel}
 \usepackage{setspace}
 \usepackage[backend=bibtex,style=chem-angew,citestyle=numeric-comp]{biblatex}
 \addbibresource{biblio} 
\usepackage{csquotes}
\usepackage{titlesec}
 \usepackage{tocloft}
  \begin{document}
 \cite{debabrata_bhadra_synthesis_2011} % this reference actually does EXIST
  \end{document}

E então copio a referência:

   @article{debabrata_bhadra_synthesis_2011,
title = {Synthesis of {PVDF}/{BiFeO}3 Nanocomposite and Observation of Enhanced Electrical Conductivity and Low-Loss Dielectric Permittivity at Percolation Threshold},
volume = {50},
doi = {10.1002/polb.23041},
pages = {572--579},
journaltitle = {{JOURNAL} {OF} {POLYMER} {SCIENCE} {PART} B: {POLYMER} {PHYSICS}},
shortjournal = {J. Polym. Sci., Part B: Polym. Phys.},
author = {{Debabrata Bhadra} and {Md. G. Masud} and {S. Sarkar} and {J. Sannigrahi} and {S. K. De} and {B. K. Chaudhuri}},
date = {2011-11-21},
file = {PVDF  BiFeO3 intro OK.pdf:C\:\\Users\\L-COM\\AppData\\Roaming\\Zotero\\Zotero\\Profiles\\wvijlgbz.default\\zotero\\storage\\I7SAEGPC\\PVDF  BiFeO3 intro OK.pdf:application/pdf}
}

Isso acontece com todas as referências que tenho na bibliografia. Aqui vai o relatório de erros:

Muito obrigado!

Algumas sugestões:

  • adicione a instrução \printbibliographyonde a bibliografia deve ser impressa

  • mudar \addbibresource{biblio}para\addbibresource{biblio.bib}

  • remova as chaves internas dos campos authorejournaltitle

  • certifique-se de executar o BibTeX e depois o LaTeX mais duas vezes.

Com essas alterações, a bibliografia de um item deverá ficar assim:

insira a descrição da imagem aqui
